Accurate design of drip irrigation systems requires sufficient understanding of horizontally and vertically distribution of water flow in soil and modeling the wetting pattern dimensions created under the drip source. Field and laboratory activities are not suitable for this purpose considering their time and financial constraints and it is necessary to apply accurate software for determination...
FARM-SCALE PROCESSING TOMATO PRODUCTION USING SURFACE AND SUBSURFACE DRIP IRRIGATION AND FERTIGATION
Environmental factors and human activities play important roles in carbon fixation and emissions generated from croplands. Eddy covariance measurements in a drip-irrigated, film-mulched cotton field were used to analyze the relationships between carbon fluxes and environmental factors in Wulanwusu, northern Xinjiang, an arid region of Northwest China. Our results showed that the cumulative net ...
Alternatives to reduce or modify nematicide use for minimizing groundwater contamination in Easter lily were explored in two field trials. Alternatives to standard 1,3-dichloropropene (1,3-D) plus phorate injection in the first trial were: (i) delaying applications until after winter rains, (ii) removing roots from planting stock, (iii) 1,3-D via drip irrigation, (iv) a chitin-urea soil amendme...
Purpose: to determine dependencies and develop a methodology for calculating the geometric dimensions constructing outline of local moisture contours formed in soil space during drip irrigation. Materials methods. The factual basis development was data full-scale (field) measurements drip-moistened their office processing. studies were carried out on experimental sites with different cover, rep...
