This work evaluated the debromination and uptake of 14C-labeled BDE-209 in rice cultivars grown in anoxic soil for 120 days (d) followed by cultivation of vegetables (peanut, eggplant and pepper) in oxic soil (120 d). Degradation of BDE-209 to lower polybrominated diphenyl ethers (PBDEs) occurred in cultivated soils, and more metabolites were released ...

ESTIMATING THE VALUE OF SEQUENTIAL UPDATING SOLUTIONS FOR INTRAYEAR CROP MANAGEMENT
1989Results of comparing updating versus nonupdating modeling assumptions call into question the use of models based on nonupdating strategies as valid representations of actual farmer actions. If farmers are sequential updaters, the results indicate that models assuming no updating are inaccurate. The degree of this inaccuracy ranges between 4% and 10% of

Agronomic efficiency of organomineral fertilizer in sequential grain crops in southern Brazil
Agronomy Journal, 2020AbstractThe use of organomineral fertilizers in agriculture instead of mineral fertilizers is a way to add organic compounds to the soil, potentially improving its properties and crop production. Our objective was to evaluate the agronomic efficiency of an organomineral fertilizer manufactured from poultry litter and mineral fertilizers. The experiment

A study was undertaken by replacing one of the cereal crops rice (Oryzn sarivn L.) or Xvheat (Trilicun~ nestivu~ii L. emend. Fiori & Paol.) by a grain legume crop or to introduce summer green- manure crop (Sesbarzin) in the sequence. Over 5 years period wheat yield was higher by 0.71 tonneha after pigeonpea [Cnjmlus cnjnr~ (L.) Millsp.] compared ...

Nitrogen Fertilization Practices for Sequential Cropping of Wheat, Turnips, and Sweet Corn
Soil Science Society of America Journal, 1984Abstract The fertilizer requirement for multiple or sequential cropping needs to be better defined. Therefore, a three‐crop field experiment was conducted on a Warden silt loam (coarse‐silty, mixed mesic, Xerollic Camborthids) to study the effects of preplant soil mineral N and rates of applied N on yield and N ...
