Abstract:
... If agronomy in the future is to make the rapid progress that has been made in the past, if it is to retain its present standing in the rapidly developing field of agriculture, if it is to accept its opportunity to render to society the service that the future will afford, a greater effort must be exerted among agronomists to secure the proper, fundamental training for their work. There must be dev ...

Abstract:
... Fertilizer nitrogen is subject to loss from the soil-root zone, and immobilization by the soil and rhizosphere microfloras, which can result in low recovery and use efficiency of the applied nitrogen. With increasing rates of application, fertilizer nitrogen efficiency decreases progressively, while leaving an increasing amount of unused nitrogen as a potential pollution hazard. Since the point of ...

Abstract:
... Pesticide use in the United States is concentrated in the Corn Belt, mainly in the form of herbicides on corn (Zea mays) and soybean (Glycine max). If this chemical load to the environment is to be reduced, without appreciably affecting crop yields, an intimate understanding of weed ecology is necessary. For annual weeds in the U.S. Corn Belt, critical ecological information includes seedbank dens ...

Abstract:
... Research techniques that have greatly advanced agronomic science in the 20th century, and have enhanced our knowledge of cause and effect, have been accompanied by reductionism. As a result, much valuable research has been accomplished, but less synthesis of results has occurred that provides answers to landscape-level research questions. We propose that a systems approach to the study of soil and ...

Abstract:
... In tropical rice (Oryza sativa L.) lowlands, soil NO₃ is lost during the transition from the dry to the wet season. To understand how soil and crop management influences NO₃ loss, we examined NO₃ dynamics during a 2-yr period in an Alfisol in the Philippines: weedy, weed-free, and frequently tilled main plots during the February to May dry season (DS), and Sesbania rostrata (Brem. & Oberm), mungbe ...
