Aquacrop—the FAO crop model to simulate yield response to water
This article introduces the FAO crop model AquaCrop. It simulates attainable yields of major herbaceous crops as a function of water consumption under rainfed, supplemental, deficit, and full irrigation conditions. The growth engine of AquaCrop is water-driven, in that transpiration is calculated first and translated into biomass using a conservative, crop-specific parameter: the biomass water ...

Effect of irrigation with secondary treated effluent on essential oil, antioxidant activity, and phenolic compounds in oregano and rosemary
Shortage of water throughout the world dictates utilization of marginal water for irrigation. Treated urban wastewater is a common alternative water source for irrigation in arid and semiarid regions. In this study we aimed to evaluate the effect of irrigation with secondary-treated effluent on plant development, essential oil yield, antioxidant activity and selected antioxidant phenolic ...

Impact assessment of pre- and post-sown irrigation with Post Methanation distillery Effluent on soil health and crop yield
Field experiments were conducted to assess the optimum dilution of Post Methanation distillery Effluent (PME) to utilise as an organic nutrient source for growing rice and wheat crops. Dilution levels of distillery effluent significantly affected the biomass production as well as grain yield of rice and wheat crops. Levels of organic carbon and NPK were significantly higher in effluent treated ...

Soil carbon levels in irrigated western corn belt rotations
Proposals promoting the use of massive amounts of crop residues and other lignocellulosic biomass for biofuel production have increased the need for evaluation of the sustainability of cropping practices and their effect on environment quality. Our objective was to evaluate the effects of crop rotation and N fertilizer management and their stover production characteristics on soil organic carbon ...

Modeling Nitrogen and water management effects in a Wheat-Maize double-cropping system
Excessive N and water use in agriculture causes environmental degradation and can potentially jeopardize the sustainability of the system. A field study was conducted from 2000 to 2002 to study the effects of four N treatments (0, 100, 200, and 300 kg N ha–1 per crop) on a wheat (Triticum aestivum L.) and maize (Zea mays L.) double cropping system under 70 ± 15% field capacity in the North China ...

Farming Innovation: From Ammonia to AgTech Software
Just over a century ago, the Haber-Bosch process was invented in Germany, enabling the scalable production of copious amounts of ammonia for the very first time. This 1910 Eureka! moment meant farmers could fertilize their crops unlike ever before, growing food on a massive scale. So massive, in fact, a population explosion ensued – humankind went from 1.6 billion in 1900 to 7.7 billion in ...
