Soil nitrogen pools, forms, and losses in mature miscanthus x giganteus under nitrogen fertilization treatments
… of N and labile carbon were not affected by fertilization treatments in this study but sites with greater potential mineralization and labile carbon showed a greater microbial activity according to FDA results. However, it would be necessary to compare results of this analysis periodically to …

Forage Systems for the Southeastern United States: Crabgrass and Crabgrass-Lespedeza Mixtures
… the effects of lespedeza seeding rate and N fertilization treatment on the yield, botanical composition, and nutritive value of crabgrass-lespedeza mixtures. A greenhouse study was conducted using three soil pH levels of 4.8, 5.5, and 6.3. Crabgrass germination and root and shoot yields were …

The relationship of chlorination and protein and lipid content to baking quality of soft wheat flour
… soft red winter wheat, was grown under different fertilization treatments involving rate and application time to alter protein content. One-half of all flour treatments were subjected to chlorination. The lipid and protein content, gliadin and glutenin composition, microstructure, rheological …

Crop Rotations for Sustainable Intensification
… in winter crops and under low to moderate N fertilization levels. Diversified crop rotations that included non-cereal crops, catch crops, and spring-sown crops improved NUE, yield stability, and the productivity of winter wheat and winter oilseed rape. In contrast, cereal-dominated rotations …

The incidence of ectomycorrhizae by Pisolithus tinctorius on Quercus rubra seedlings fertilized with sodium nitrate and ammonium chloride
… as sodium nitrate or as ammonium chloride; (3) fertilization at 15 days or at 40 days after planting of seed; (4) rates of nitrogen applied at 0.0, 0.0133, 0.0266, or 0.0532 g N per seedling; and (5) the seedlings grown for 60, 100, or 140 days. All 960 seedlings were grown in a …

Controlling Growth in Echinacea Hybrids
… flowers and shoot dry weight. In overwintering, fertilization treatments that resulted in low substrate electrical conductivity going into dormancy, 5.0 kg·m controlled release fertilizer 15N-3.9P-10K or 150 mg·L⁻¹ N using 15N-2.2P-12.5K applied using constant liquid feed, resulted in the highest …

Uptake of native and applied copper by corn and wheat as related to soil properties
… the Cu in the labile pool, whereas CuSO₄ fertilization did not affect Zn in the labile pool. A greenhouse experiment was conducted to examine the response of wheat to Cu application on 14 soils. Treatments in this study were a control and 5.35 mg Cu kg⁻¹ as CuSO₄. Dry matter yields were …

Polyhalite alters the uptake and partitioning of mineral nutrients in corn
… at physiological maturity. All of the potassium fertilization treatments resulted in significantly greater above ground dry weight accumulation compared to the unfertilized control, but season-long plant accumulations of potassium and sulfur were greater in response to all treatments containing …

Aðstoð við myndun lífrænnar jarðvegsskánar við endurheimt vistkerfa á Íslandi
Lífræn jarðvegsskán eða lífskurn (e. biocrust) er verið mikilvægur vistmeitill sem bætir virkni, stöðugleika og frjósemi jarðvegs og getur stuðlað að landnámi æðplantna. Hún getur því gengt mikilvægu hlutverki við baráttu gegn jarðvegseyðingu og endurheimt vistkerfa. Í þessari rannsókn var kannaður …
