At Florida's southeastern tip, sweet corn (Zea Mays) is grown commercially during winter months. Most fields are treated with atrazine (6-chloro-N-ethyl-N'-[1-methylethyl]-1,3,5-triazine-2,4-diamine). Hydrogeologic conditions indicate a potential for shallow groundwater contamination. This was investigated by measuring the parent compound and three degradates--DEA (6-chloro-N-[1-methylethyl]-1,...

The strategic management of agricultural lands involves crop field monitoring each year. Crop discrimination via remote sensing is a complex task, especially if different crops have a similar spectral response and cropping pattern. In such cases, crop identification could be improved by combining object-based image analysis and advanced machine learning methods. In this investigation, we evalua...

Abstract Intensive vegetable crop rotations can have detrimental effects on soil health, draining of organic matter reserves and necessitating nitrogen (N) inputs. In addition, many leave little time or space to integrate beneficial arthropod pollinator habitat into rotations; the lack may cause declines in arthropods, which lead insufficient pollination services increased pest pressure. Nine t...

It has been established that on each variant oftillage use of mineral fertilizers have a positive effect the structural indicators yield when sowing summer soybeans. When soil was cultivated to depth 8–10 cm, number beans per plant 3.0–10.2 pieces, grains 5.7–21.8 grain 1.0–3.6 g, weight 1000 7.0–7.4 g; disking 13–15 cm these reached, respecttively, 3.3–11.4 6.0–22.5 1.2–3.8 3.5–8.0 plowing 20–...

efficient use of inputs and energy resources is one of the most important principals of sustainable agriculture. for this purpose, water and energy productivity of irrigated agroecosystems of major crops in kermanshah province were evaluated. the data was collected via questionnaire through face to face interview of 180 farmers of this province during summer 2010. results showed that water prod...

A pot experiment to determine the effects of summer cover crops and soil amendments on okra yields and population densities of various soil nematode taxa was conducted in two consecutive growing seasons in a subtropical region. Two cover crops, sunn hemp (Crotalaria juncea) and sorghum sudangrass (Sorghum bicolorrS. bicolor var. sudanense), were grown and returned to the soil with fallow as a c...
