In a ten‐year study of potassium (K) and lime application to a Kalmia sandy loam (fine‐loamy, siliceous, thermic Typic Hapludult), a soil high in nonexchangeable K, corn (Zea mays L.) and soybean [Glycine max (L.) Herr.] have not responded to app

We investigated the effect of temperature on K availability using quantity-intensity (Q/I) analyses and on K selectivity on the Ap and B21t horizons of a Kalmia sandy loam (Tppic Hapludults), an Evesboro loamy sand (Typic Quartipsamments), and a Mata

(...) Corn grain yields in the low-input systems were 75% of conventional in 1981 to 1984, but yields were not significantly different in 1985. Weed competition and insufficient N limited low-input corn yields during the first 4 yr. Soybean yields in

Leaf samples of Ilex opaca ‘Miss Helen’ were collected over a 2-month period and analyzed on a mg/g basis for total nonstructural carbohydrates (TNSC), individual ethanol soluble sugars (IESS), total ethanol soluble sugars (TESS) and apparent sto
