Effect of irrigation with anaerobic baffled reactor effluent on Swiss chard (Beta vulgaris cicla.) yield, nutrient uptake and leaching
The disposal of treated wastewater from an anaerobic baffled reactor (ABR) effluent into water bodies can cause pollution. Treated wastewater management through irrigation of crops has the potential of increasing crop production through nutrient uptake while reducing the risks of environmental pollution. However, this study aimed to investigate the effect of irrigation with ABR effluent on ...

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 ...

Irrigated, no-till corn and barley response to nitrogen in Northern Colorado
Converting irrigated, conventional-till (CT) systems to no-till (NT) production systems can potentially reduce soil erosion, fossil fuel consumption, and greenhouse gas emissions. Nitrogen fertilization effects on irrigated corn (Zea mays L.) and malting barley (Hordeum distichon L.) yields in a corn-barley rotation were evaluated for 6 yr on a clay loam soil to determine the viability of using a ...

Evaluation of the AquaCrop model for simulating yield response of winter wheat to water on the southern Loess Plateau of China
The objective of this study was to evaluate the performance of the FAO-AquaCrop model in winter wheat in the southern Loess Plateau of China. Multi-year field experimental data from 2004 and 2011 were used to calibrate and validate the model for simulating biomass, canopy cover (CC), soil water content, and grain yield under rainfed conditions. The model performance was evaluated using root ...

Corn cob characteristics in irrigated central great plains studies
Escalating fossil fuel cost and concern over global climate change have accelerated interest in cellulosic feedstocks, such as corn (Zea mays L.) cobs, for liquid fuel production. Little information is available about this plant organ. We compiled and summarized available cob data from several recent field studies in the Central Great Plains. Data were collected from two locations in Colorado and ...

Potato response to a polymer-coated urea on an irrigated, coarse-textured soil
Controlled release fertilizers, especially polymer-coated urea (PCU), have been shown to reduce nitrate (NO3) leaching while maintaining potato (Solanum tuberosum L.) yields, but cost has been prohibitive. A new type of PCU (Environmentally Smart Nitrogen, Agrium, Inc., Calgary, AB) is less costly than previous PCUs, but its effectiveness on potato production has not been extensively studied. A ...

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 ...

Nitrogen, tillage, and crop rotation effects on carbon dioxide and methane fluxes from irrigated cropping systems
Received for publication December 15, 2008. Long-term effects of tillage intensity, N fertilization, and crop rotation on carbon dioxide (CO2) and methane (CH4) flux from semiarid irrigated soils are poorly understood. We evaluated effects of: (i) tillage intensity [no-till (NT) and conventional moldboard plow tillage (CT)] in a continuous corn rotation; (ii) N fertilization levels [0–246 kg N ...

How to maintain soil fertility
In order to maintain soil fertility, some low-yield soil (acid soil, alkali soil and salt soil), chemical improvers and irrigation should be used to improve, remove obstacles and improve the fertility level. In addition, reasonable cultivation and rotation should be carried out to regulate the nutrients and water in the soil and prevent some nutrient deficiency and water vapor imbalance. 1. ...

Full Planet, Empty Plates: Chapter 2. The Ecology of Population Growth
Throughout most of human existence, population growth has been so slow as to be imperceptible within a single generation. Reaching a global population of 1 billion in 1804 required the entire time since modern humans appeared on the scene. To add the second billion, it took until 1927, just over a century. Thirty-three years later, in 1960, world population reached 3 billion. Then the pace sped ...
