A simple spectral index using reflectance of 735 nm to assess nitrogen status of rice canopy
Spatial distribution of canopy N status is the primary information needed for precision management of N fertilizer. This study demonstrated the feasibility of a simple spectral index (SI) using the first derivative of canopy reflectance spectrum at 735 nm (dR/d|735) to assess N concentration of rice (Oryza sativa L.) plants, and then validated the applicability of a simplified imaging system ...

Do mixed-species legume fallows provide long-term maize yield benefit compared with monoculture legume fallows?
The deliberate planting of fast-growing N2–fixing legume monoculture species in rotation with cereal crops can be an important source of N for soil fertility replenishment. We hypothesized that mixed-species fallows have a higher potential of giving long-term residual benefits in terms of biomass, nutrients, and quality of residuals leading to long-term nutrient supply to postfallow maize (Zea ...

Sound Advice: Meeting Corn`s Nutrient Demands
In this edition of Sound Advice, Will Llewellyn, Sales Agronomist, shares his insights on how growers can meet corn’s nutrient demand all season long. Early in the crop’s life, nutrient needs increase slowly, until corn reaches the V10 to V14 window of peak nutrient demand. By the end of that window, much of the fertilizer applied since last fall has run its course. Fertilizer ...

Land application of sugar beet by-products: effects on Nitrogen mineralization and crop yields
Land application of food processing wastes has become an acceptable practice because of the nutrient value of the wastes and potential cost savings in their disposal. Spoiled beets and pulp are among the main by-products generated by the sugar beet (Beta vulgaris L.) processing industry. Farmers commonly land apply these by-products at rates >224 Mg ha–1 on a fresh weight basis. However, ...

Novel simulation-based algorithms for optimal open-loop and closed-loop scheduling of deficit irrigation systems
The scarcity of water compared with the abundance of land constitutes the main drawback within agricultural production. Besides the improvement of irrigation techniques a task of primary importance is solving the problem of intra-seasonal irrigation scheduling under limited seasonal water supply. An efficient scheduling algorithm has to take into account the crops' response to water stress at ...

Dryland crop yields and soil organic matter as influenced by long-term tillage and cropping sequence
Novel management practices are needed to improve the declining dryland crop yields and soil organic matter contents using conventional farming practices in the northern Great Plains. We evaluated the 21-yr effect of tillage and cropping sequence on dryland grain and biomass (stems + leaves) yields of spring wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and pea (Pisum sativum L.) and ...

The 1996 “Freedom to Farm” Farm Bill
The period of U.S. farm bills where the instruments were designed around compensation policies that used price support/supply management programs allowing farmers to remain in production during long periods of low prices—the result of four centuries of publicly-sponsored developmental policies—ended with the adoption of the 1996 Farm Bill. In some important ways, the demise of price ...
