Adoption of drip irrigation in Kerala State of India is very low and potential exists toincrease its adoption in the State. A field survey was conducted in two districts to determine themajor factors influencing farmers’ adoption of drip irrigation and to draw conclusions that willhelp in developing policy and institutional interventions to encourage the adoption. The resultsindicated that adop...

Understanding the formation and spatial-temporal distribution of soil salt crusts (SSCs) is important for the sustainable management of the artificial shelterbelt and high-salinity groundwater utility in the Taklimakan Desert in Northwest China. The SSCs in this area were sampled, and their thickness and electrical conductivity (EC) were analyzed to examine the formation mechanism and the spati...

Nitrogen compounds added to the soil may convert nitrate and cause contamination. The distribution uniformity of in surface vs. subsurface drip irrigation systems were compared a physical model consisting transparent glass box (1.20 x 0.5 1 m) sandy loam soil, considering emitter installation depths 0 30 cm, discharge rates Q1 = 2, Q2 4, Q3 8 L/h, fertilizer levels S1 125, S2 250, S3 375 mg/L. ...

The extensive use of pesticides in agriculture is compromising soil and water quality. One major concern is protecting water resources from contamination. The main objective of this research was measuring 2,4- D in a silty clay soil and simulating temporal transportation of this herbicide in soil using a LEACHP model, in a corn root zone field. 2,4- D was applied at 3.5 kg a.i./ha, followed by ...

Coastal bermudagrass (Cynodon dactylon L.) may be a potentially important source of bio-based energy in the southern US due to its vast acreage. It is often produced as part of a waste management plan with varying nutrient composition and energy characteristics on fields irrigated with livestock wastewater. The objective of this study was to determine the effect of subsurface drip irrigation wi...

Drip irrigation is a means of distributing the exact amount of water a plant needs by dripping water directly onto the root zone. It can produce up to 90% more crops than rain-fed irrigation, and reduce water consumption by 70% compared to conventional flood irrigation. Drip irrigation may enable millions of poor farmers to rise out of poverty by growing more and higher value crops, while not c...
