Soil Moisture Potential: Understanding the Foundation of Plant Hydration

Soil Moisture Potential: Understanding the Foundation of Plant Hydration

This article provides an overview of soil moisture potential, addressing common inquiries and highlighting its significance in agricultural and environmental contexts. For a deeper dive into the subject, readers are encouraged to consult academic literature and professional resources.

Soil moisture potential, a critical concept in agronomy and water management, is the measure of the energy status of water in soil. It’s essential for predicting water availability to plants and understanding soil water processes. Here, we address the top seven questions often asked about soil moisture potential.

  1. What is Soil Moisture Potential? Soil moisture potential, also known as soil water potential, is the potential energy of water in soil compared to pure, free water. It’s measured in units of pressure, such as bars or kilopascals (kPa), and indicates how easily plants can extract water from the soil. The drier the soil, the higher the soil moisture potential, meaning more energy is required for plants to absorb water.
  2. Why is Soil Moisture Potential Important? Understanding soil moisture potential is vital for effective irrigation management, predicting plant water stress, and optimizing crop yield. It helps determine when and how much to water, ensuring that plants receive adequate hydration without wastage.
  3. How is Soil Moisture Potential Measured? Several methods measure soil moisture potential, including tensiometers, psychrometers, and resistance blocks. These instruments gauge the force required to extract water from the soil, providing a direct measurement of soil moisture potential.
  4. What Factors Affect Soil Moisture Potential? Soil texture, structure, organic matter content, and salinity are key factors influencing soil moisture potential. For instance, sandy soils typically have lower moisture potential than clay soils, affecting water availability to plants.
  5. How Does Soil Moisture Potential Relate to Plant Water Uptake? Plants absorb water from the soil through their roots, driven by the difference in water potential between the soil and the plant. A lower soil moisture potential means that water moves more readily into plant roots, facilitating hydration.
  6. Can Soil Moisture Potential Predict Drought Conditions? Yes, monitoring soil moisture potential can indicate impending drought conditions. A sustained high soil moisture potential suggests that soil water is becoming increasingly unavailable to plants, signaling potential water stress.
  7. What is the Role of Soil Moisture Potential in Soil Hydrology? Soil moisture potential plays a crucial role in soil hydrology by influencing water movement within the soil profile. It affects infiltration, percolation, and the overall water balance in the ecosystem.

Farmers can optimize irrigation by utilising soil moisture potential in several ways:

  1. Monitoring Soil Moisture Levels: By regularly measuring soil moisture potential, farmers can determine the precise timing for irrigation, ensuring that plants receive water only when necessary.
  2. Using Sensors: Implementing soil moisture sensors can help farmers monitor real-time soil moisture levels. These sensors can measure both soil water potential and soil water content, providing valuable data for irrigation decisions1.
  3. Understanding Crop Requirements: Different crops have varying water needs. Farmers can use soil moisture potential data to tailor irrigation schedules according to the specific water requirements of each crop.
  4. Adjusting Irrigation Based on Weather Conditions: Weather patterns significantly affect soil moisture. Farmers can adjust irrigation practices based on forecasted weather to prevent over-irrigation or water stress.
  5. Implementing Automated Irrigation Systems: Automated systems can be programmed to irrigate based on soil moisture potential thresholds, ensuring efficient water use and reducing labour costs.
  6. Improving Soil Health: Healthy soil retains water better. Farmers can enhance soil organic matter and structure to improve water retention and reduce the need for frequent irrigation.
  7. Educating on Best Practices: Farmers can benefit from training on the latest irrigation techniques and technologies that utilize soil moisture potential for water conservation and crop yield optimization2.

By integrating soil moisture potential into their irrigation strategies, farmers can conserve water, reduce costs, and increase crop yields, contributing to sustainable agricultural practices.

In conclusion, soil moisture potential is a fundamental parameter in agronomy, directly impacting plant growth, soil health, and water conservation efforts. By understanding and monitoring this property, agronomists and water specialists can make informed decisions to support sustainable agricultural practices and ensure water security for future generations.

Pistachio Crops

Commercial Pistachio Orchard Pilot Loxton, South Australia

Commercial Pistachio Pilot

Autumn 2024 | Loxton, SA

The Brief

A vertically integrated agricultural production company, producing Pistachios in the Loxton Region of South Australia, with interest and control from paddock to plate.

They use state-of-the-art technology to effectively produce Pistachios and are an emerging layer in the Pistachio industry. To date this enterprise has been using standard irrigation process for its Orchards. There are multiple challenges about water availability especially during the dry season.

This Orchard is positioned in the lower basin of the Murray Darling Basin on the Murray River and covers some 50 hectares of Pistachios. It has a mix of flat and gently undulating topography and sandy loam soils.

This area has historically, and continues to, face significant challenges around water availability, water quality, energy pricing and environmental impact of agricultural production on the ecosystem as a whole alongside the traditional natural disaster risks arising from climate extremes of drought and flood.

Pistachios are a medium-volume water use crop and there is a lot of focus on the industry at the moment and its social license to operate because of the high volumes of water it takes to produce and the challenges of the ecosystem around current and future water availability. 

The river system is currently estimated to be facing a 20% loss of water volume in the coming years due to climate related factors. Producers reliant on this ecosystem must find ways of doing more with less if they are to maintain let alone grow their production.

The regional Irrigation Trusts, which manage the water delivery infrastructure to the farm, and farms in the region, are currently facing a multitude of challenges and whilst there are initiatives in development, there is a significant risk to the enterprise and other producers in the area, who form co-operatives that owns the infrastructure which is managed by the Trust.

The Trust is charged with the management and upkeep and in ensuring water availability. These challenges could have major impacts on the enterprise’s business related to the cost of delivered water cost and overall security of supply and water quality.

The use of fertigation in the production of Pistachios is significant. The rising costs of fertilisers and environmental impacts of leaching is another area of focus for improvement including reduced volume and cost whilst maintaining or increasing yields and reducing environmental impacts.
The enterprise also manages a common Pistachio production challenge of fungal diseases and more which negatively impact production.

Overall, the enterprise has, and continues to take, a strong and active leadership role by searching and trialling new ways to address this and other issues.

The decades of experience and high levels of expertise that exists within the enterprise team, together with the dedication to the present success and future success of the business, the Pistachio industry, coupled with the awareness of its role within the local communities, and the broader regional ecosystem in the Riverlands and ultimately as part of the South Australian national horticulture industry and that of the vast Murray Darling Basin ecosystem is a pivotal one.

The Project

The Pilot Plot is on an undulating site and the irrigation solution with Growstream has been designed accordingly by the Inhouse design team in Nested Ventures and RDI and in collaboration with the Technical Officer and CEO of the enterprise.

One row of Growstream will be implemented on either side of the trees at 30cm spacings with a distance of approximately 40cm from the trunk.

Water will be delivered to the pilot from a header tank which has been sized accordingly to the maximum current known water requirements of the trees involved in the Pilot. Water will be delivered through a gravity fed system and maintained at 2psi or less 24hrs a day x 7 days a week. Fertigation will be delivered through the system with an immediate decrease in volume of 50% of fertiliser.

The Pilot will include one variety of Pistachios only the Australian Sirora variety which have been bred by the CSIRO for Australian conditions.

The trees are approximately 3 years of age and will be monitored throughout the Pilot with regular reporting on performance of the system and of the trees.

The RDI Australia team and the International RDI Team will be delivering pre-implementation training and on-site implementation support during installation. Working with the enterprise’s in-house and external resources for the physical implementation. We will be posting updates on the Pilot including installation and updates throughout 2024.

Overview

Location: Salinas, CA

Environment: Outside
Temperatures: Average low / high = 51 / 74° F (notable heatwave in Sept)

Rainfall: 0.04”

Plant Life: Organic Romaine Hearts

Planting: Transplant
Duration: 42 Days (Aug - Oct)

Soil: Chualar Loam
Planting Size: Three beds, average 225 ft each. Total of 10.3% Acre

Plant Spacing: 80” beds. 6 plant rows per bed
Injection Method: Tractor and Injection Implement. Single bed, three lines

Fertilization: Certified Organic chicken manure
RDI Version: 5/8” Single Sided Responsive

Summary

Responsive Drip Irrigation (RDI) worked with a Commercial Grower in Salinas, CA to perform a field trial comparison of RDI’s GrowStream™ plant-responsive irrigation system versus standard drip tape irrigation to produce Organic Romaine Hearts.

The trial ran from August to October of 2017. The standard practice for the Commercial Grower for this crop in this field requires two fertilizer applications: the first is pelletized organic chicken manure mixed into the soil prior to planting.

The second application is equal in amount; however, it is applied to the surface approximately two weeks after planting the transplants. The grower’s focus was to eliminate the need for a second fertilizer application, which would reduce their labour and material cost. The performance metric for RDI’s responsive irrigation system to achieve in this comparative field trial required that RDI’s system produce a high-quality crop while reducing the amount of the grower’s standard organic fertilizer application.

The well water that serves the trial field is high in nitrogen. RDI’s unique water delivery can reduce the total water required, but also more effectively utilizes the available nitrogen found in the water.

For this trial RDI did NOT receive the second application of fertilizer. In this comparative trial, a similarly sized grower control plot also did not receive the second fertilizer application, referenced as Control Group 1 (CG1). The remainder of the field received the standard practice of two fertilizer applications, referenced as Control Group 2 (CG2).

For irrigation of this crop, the standard practice is to apply 4 acre-inches with sprinklers for stand establishment. Another 10 acre-inches is then applied with surface drip tape for the remainder of the crop, for a total of 14 acre inches. The crop was harvested at 42 days.

The GrowStream™ plant-responsive irrigation system significantly reduced fertilizer use by 50% and water use by14%. RDI produced an excellent crop with comparable yield and generally taller plants compared to the Commercial Grower’s standard practice (CG2).

Due to logistical constraints, the RDI trial area received all the standard sprinkler water applications. Sprinkler water applications are not required to establish transplants with RDI’s system, so additional water savings would be evidenced without the use of sprinkler events.

In summary, this trial demonstrated that RDI GrowStream™ plant-responsive system exceeded the grower’s expectations, producing a higher quality crop compared to both of the grower’s control groups while reducing fertilizer and water use.

Significant Fertilizer and Water Savings

In Control Group 2 (CG2) the Commercial Grower made the standard second application of chicken manure fertilizer. A truck filled the three large “hoppers”. The operator then travelled the length of the beds with a tractor, and applied on the surface between each pair of plant lines.

Photo shows CG2 and typical surface application of chicken manure fertilizer.

RDI and CG1 were excluded from this second application.

The second application is 50% of the total fertilizer typically used by the Commercial Grower

RDI used just under 12 acre-inches per acre vs. 14 acre-inches for the standard application, a 15%savings. RDI’s water usage during the first 10-14 days was higher than the Control Groups due to the additional water applied to RDI’s trial beds from the grower’s sprinkler applications. Because of the zones and area size of sprinkler coverage, it was not possible to exclude RDI’s trial beds from receiving the 4 acre-inches of sprinkler events. This excessive water from the sprinklers causes leeching of the existing nutrients in the soil that were applied pre-plant.

RDI’s plant-responsive system is designed to function without the need for sprinkler use. RDI system’s initial 10-14 day water delivery is sufficient to meet the needs of both transplant establishment and seed germination.

Thus, compared to the standard application of 14 acre-inches, the 8 acre-inches applied via RDI drip tape would show a total water savings of 43%.

Day 5. RDI’s three beds are centre of photo. Each bed has 6 plant lines. CG1 has three beds to the left, and the remainder of the field is CG2. Grower is using sprinklers for stand establishment. Due to sprinkler spacing requirements, RDI could not be excluded from sprinkler irrigation events.

Day 33. Comparative photos and measurements of AVERAGE PLANT HEIGHT:CG1: 10.4” (left), RDI: 12” (centre), CG2: 10.8” (right)

Day 40. Harvest has begun at the south end of field. RDI trial section shows excellent growth and development, and continues to be the tallest section in the field.

Day 42: Harvest. Multiple sample plants were cut from comparable sections. The largest plant in each section was cut, the outer leaves removed, and then sliced in half to view plant growth and development. RDI’s crop showed taller growth compared to CG1 and CG2, despite receiving half the fertilizer of CG2 and using less water.

Day 42: Plant sizes prior to harvest: Samples from each of the sections were measured for height and width. CG2 was wider than RDI by a slight margin of 0.52”. The RDI plants were substantially taller than both CG1 and CG2, 1.62” and 1.17”, respectively.

Benefits of Optimum Moisture Content: A Comprehensive Analysis for Almond Trees

Managing Challenges Unique to Almond Trees

Almond trees (Prunus dulcis) present distinct challenges that require precise water management strategies. The cultivation of almond trees is susceptible to a range of environmental factors, including water stress, waterlogging, and associated microbial threats. Optimal moisture content plays a pivotal role in mitigating these challenges and ensuring the health and productivity of almond orchards.

Hull Rot: A Waterlogging-Related Threat

Hull rot (caused by the fungus Rhizopus stolonifer) is a prevalent concern in almond orchards, particularly in waterlogged conditions. This destructive pathogen thrives in environments with excess moisture, such as waterlogged soils. Hull rot affects almond fruits by causing rapid decay and rendering them unmarketable. The disease progresses swiftly, posing a considerable risk to almond yield and quality. The prevention of waterlogging is, therefore, a critical factor in averting hull rot outbreaks

Waterlogged Conditions and Specific Fungal and Bacterial Pathogens

Waterlogged soils create an ideal habitat for a range of fungal and bacterial pathogens that can devastate almond trees. Notably, Phytophthora spp. fungi, including Phytophthora cinnamomi, thrive in saturated soils and attack the root system, leading to root rot and reduced nutrient uptake. Additionally, waterlogged conditions encourage the growth of anaerobic bacteria that contribute to crown gall disease, impacting the tree's vascular tissues.

RDI Growstream's Role in Almond Tree Resilience

Comparison with Conventional Irrigation Systems: Implications for Waterlogging and Soil Moisture

Almond orchards have historically employed various irrigation systems, each with its advantages and limitations. Understanding how different irrigation methods impact soil moisture levels and correlate to waterlogging, dry soils, and overall plant health is essential for effective water management.

Surface Sprinkler Irrigation

Surface sprinkler irrigation involves distributing water over the orchard using sprinklers, simulating natural rainfall. While this method is convenient and covers a large area, it is prone to water wastage through evaporation and runoff. Excessive water application can lead to waterlogging in certain areas, creating conditions favorable for fungal and bacterial pathogens. Additionally, uneven distribution may result in overhydration in some parts of the orchard and insufficient moisture in others.

Standard Drip Irrigation

Standard drip irrigation is a more targeted approach that delivers water directly to the root zone of plants. While this method reduces water wastage compared to surface sprinklers, it still requires careful monitoring to prevent overwatering or underwatering. Overwatering can lead to waterlogging and encourage the growth of waterlogged-condition-specific pathogens. Underwatering can result in dry soil conditions that stress the plants and negatively impact yield.

Correlation to Soil Moisture Levels and Waterlogging

Both surface sprinkler and standard drip irrigation systems can contribute to fluctuating soil moisture levels and periods of waterlogging or dry soil conditions. In contrast, RDI Growstream Technology offers a unique advantage by delivering water only in response to the plant's exudate signals, maintaining precise moisture content around the root structures. This targeted approach minimizes the risk of waterlogging while preventing periods of dry soil that stress the plant.

Summary: Comparison with Conventional Irrigation Systems and RDI Growstream

Almond orchards have traditionally relied on diverse irrigation systems, each with distinct benefits and drawbacks. Evaluating their impact on soil moisture levels, waterlogging, and overall plant health is crucial for effective water management.

Surface sprinkler irrigation, although convenient, is prone to water wastage and uneven distribution, potentially leading to waterlogging and uneven moisture content. Standard drip irrigation is more efficient but requires careful monitoring to avoid waterlogging or dry soil.

In contrast, RDI Growstream Technology stands out by delivering water precisely in response to plant signals, maintaining optimal moisture around root structures. Unlike other systems, it sidesteps the risk of waterlogging and dry soil conditions, ensuring consistent plant health and minimizing stress. As almond orchards explore irrigation methods, RDI Growstream emerges as a water-efficient and targeted solution to maximize yield and minimize risk.
