Fertilizing for Irrigated Corn

Irrigated corn production is an important component of agricultural systems in some parts of the central and southern Great Plains of the USA. Adequate and balanced nutrient inputs are critical to pro ...

Challenges of Increasing Water and Nutrient Efficiency in Irrigated Agriculture

Robert L. Mikkelsen, Timothy K. Hartz and M.J. Mohammad Rusan

2013 Annual Interpretive Summary - Climate Change Mitigation and Adaptation through Conservation Agriculture and Precise Nutrient Management in Current and Future Cereal-based Cropping Systems of the Indo Gangetic Plains

Participatory trials in eight farmer fields in Haryana were conducted to assess the effect of nutrient and residue management on wheat yield, nutrient uptake and carbon sustainability index. Three res ...

Project Description - Determining the Environmental Optimum Rate of Fertilizer N for Irrigated Crops in the Semiarid Prairies

Objectives: The primary goal of this project is to identify the environmental optimum rate of fertilizer N (i. e. , the rate that provides the greatest yield increase with the lowest FIE) for irrigate ...

Salinity Mapping for Precision Variable Rate Fertilizer Application

The incidence of salinity affected areas in irrigated fields results in restricted crop growth in the saline areas. If fertilizer applications are a constant rate blanket application over the field, t ...

Nitrogen Management and Water Productivity of Limited Irrigation Corn

This project seeks to improve crop water productivity of irrigated maize by better understanding the interaction of nitrogen fertility management and limited irrigation.

Орошение и удобрение яблоневого сада интенсивного типа

В.В. Бородычев, А.А. Криволуцкий, А.Ф. Дружкин, Плодородие, 2012, №1, 42-45.

2010 Annual Interpretive Summary - Nitrogen dynamics under elevated carbon dioxide

The effect of elevated carbon dioxide concentration ( CO2 ) on greenhouse gas emissions from semi-arid cropping systems is poorly understood. Two studies were reported during 2010, one from the Austra ...

2009 Annual Interpretive Summary - Nitrogen dynamics under elevated carbon dioxide

The Australian Grains Free Air Carbon Dioxide Enrichment (AGFACE) facility was established to compare wheat growth, yield, and development under ambient atmospheric carbon dioxide (a CO2 ~380 ppm) and ...

Improving Nitrogen Fertilizer Management in Surface-Irrigated Cotton

We propose conducting research in central Arizona to compare the common regional practice of N fertigation with knifed N injections in surface-irrigated cotton (i.e., level furrow irrigation). Additio ...

Improving Nitrogen Fertilizer Management in Surface-Irrigated Cotton

We propose conducting research in central Arizona to compare the common regional practice of N fertigation with knifed N injections in surface-irrigated cotton (i.e., level furrow irrigation). Additio ...

Influence of phosphorus fertilizer on the soil quality of a historic irrigated rotation

Determine the influence of historic phosphorus application on soil quality and nutrient supplying power in a low input irrigated crop rotation.
