Distribution of moisture and salinity under deficit irrigation and irrigation water salinity in an alternative trickle irrigation system of tape
This study was performed to investigate the horizontal and vertical distribution of soil moisture and salinity using an alternative trickle irrigation system of drip tape. Four main treatments consisting of 100, 80, 70, and 60% of the plants’ water requirements and three sub-treatments of 2.1, 4.6, and 10.2 dS/m, were conducted. Following irrigation, the soil moisture and salinity ...

Nitrate leaching in two irrigated soils with different rates of cattle manure
Received for publication December 15, 2008. Manure applied to irrigated land may potentially contaminate groundwater with NO3–N. An 8-yr field experiment was conducted in southern Alberta, Canada, to determine the effects of different rates of manure on NO3–N accumulation in two irrigated soil types and NO3–N leaching to shallow groundwater. An annual cereal silage was grown at each site and ...

Efficient Vineyard Irrigation Series #2: How to Predict Soil Moisture for the Next Two Weeks
As viticulturists and grape growers know, understanding current and future soil moisture content is a prerequisite for taking actions to reduce crop variability, optimise water usage, and tackle irrigation problems. Adequate soil moisture is critical for ensuring fruit quality. Water stress and over-vigorous growing conditions can result in inferior fruit quality and reduce profitability. ...

Briggs and Eggers Orchards Case Study
The 400-acre Briggs and Eggers Orchards in the fertile Bonita Springs Valley of southern Arizona have been growing apples, peaches and pears since 1968. Owners Lance and Melissa Eggers and Joe and Jean Briggs have been committed to building a strong organic program with sustainable environmental practices since 1990. Granite-rich alluvial soil and moderate, high-elevation Arizona summers allow ...

The Arkansas irrigation yield contest
Most farmers are familiar with contests in which participants try to achieve the maximum yield of a crop from a given field. Fewer would be familiar with a contest in which participants’ total crop yield is divided by the amount of water they use—thus measuring their water use efficiency. That’s the kind of contest that Dr. Chris Henry and his colleagues at the University of ...

Strengthen your Seeding Strategy
On-farm weather stations and soil moisture probes take the guesswork out of seeding plans and execution As the 2023 seeding season is fast approaching, why not end the soil moisture guessing game on your farm? Especially when you have technology available to inform weather-related planning and crop management decisions. Precision crop management tools, including on-farm weather stations and soil ...

Irrigation Advances are Transforming how we Farm
The American south-west and central plains could be on course for super-droughts the like of which they have not witnessed in over a 1,000 years. Places like California are already facing very dry conditions, but these are quite gentle compared with some periods in the 12th and 13th Centuries. On this blog and elsewhere, we have often talked about having improved water efficiency as an industry ...

Efficient Vineyard Irrigation Series #3: How to dynamically optimise irrigation scheduling
As climate change increases the cost and scarcity of water, as well as consumer concerns over environmental impact, efficient irrigation is fast becoming a key component of successful vineyard management. The need for efficiency is also growing with the increased frequency of extreme weather events (e.g. extreme heat, fluctuating rainfall, bushfires and droughts), which effect vine growth and ...

Summer Irrigation Makes the Crop
Summer Irrigation Makes the Crop Summertime. At this point in the growing season, fruit for tree and vine crops has long been set. Now, the challenge is to bring as much of this yield potential to harvest, and at the desired quality. Irrigation management is crucial to achieve this goal. For most crops, irrigation should provide readily available soil moisture continuously so that fruit and ...

A root-zone soil regime of wheat: physiological and growth responses to furrow irrigation in raised bed planting in northern China
Different irrigation methods in wheat (Triticum aestivum L.) result in different water and nutrient use efficiencies and, ultimately, plant growth. A field experiment was conducted during the 2006–2007 and 2007–2008 crop cycles to investigate the effects of furrow irrigated raised bed planting and the effects of flood irrigated conventional planting on growth and productivity in winter wheat. In ...

Soil water movement under a drip irrigation double-point source
Particularly in dry regions, the scarcity of high-quality fresh water has heightened the importance of urban runoff water re-use, leading as well to the improvement of water use efficiency through the surface drip irrigation method. Given the limited research on wetting front migration under a surface drip irrigation emitter, soil water movement under a double-point-source irrigation emitter ...

Physiological interaction of soil moisture deficit and plant population on yield and yield components relationships of maize ( Zea mays L.)
Maize ( Zea mays L.) crops were grown at Coimbatore in the years 2009 and 2010 during the kharif season. The treatments imposed were three soil moisture levels: 100% irrigation water supply (0.8 IW/CPE ratio), 75% irrigation water supply (0.6 IW/CPE ratio) and 50% irrigation water supply (0.4 IW/CPE ratio). The plant density treatments adopted were normal spacing (60 × 20 cm), narrow ...

Subsurface drip and overhead irrigation: a comparison of plant boll distribution in upland cotton
Although subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops, the effects of SSD on the distribution of bolls on cotton plants (Gossypium hirsutum L.) have not been thoroughly examined. The purpose of this study was to add to the current knowledge about the effects of SSD on cotton yield dynamics. Cultivar DP 488 BG/RR was grown in three studies ...

Multisensor Capacitance Probes for Simultaneously Monitoring Rice Field Soil-Water-Crop-Ambient Conditions
Abstract: Multisensor capacitance probes (MCPs) have traditionally been used for soil moisture monitoring and irrigation scheduling. This paper presents a new application of these probes, namely the simultaneous monitoring of ponded water level, soil moisture, and temperature profile, conditions which are particularly important for rice crops in temperate growing regions and for rice grown with ...

Soil tensiometer
What is a soil tensimeter? Soil tensimeter uses the principle of negative pressure to measure soil moisture and studies soil moisture movement from the perspective of energy. Transparent PVC pipe can clearly see the amount of water, low-end with high-quality clay head, fast sealing, accurate measurement. Soil tensiometer is a practical method to measure soil condition by using a negative pressure ...
