Soil P availability limits legume persistence and distribution in the fynbos of the Cape Floristic Region
… and produce more seed. In the oligo-trophic soils occupied by fynbos, symbiotic N2-fixation enables legumes to overcome low N availability but not low P availability. I hypothesized that: legumes are less effective at acquiring P from sparingly soluble sources compared with members of …

Influence of Poultry Litter on Dark Tobacco Growth and Soil Nutrient Availability
… fertilizers increase the osmotic pressure of the soil solution and soil acidity, often causing reduced stands, Mn toxicity, Mo and Ca deficiencies, and reduced yield and quality of the cured leaf (Sims et al., 1984). Poultry litter utilized as a nutrient source is an inexpensive alternative to …

THE INFLUENCE OF PULSE CROPS ON SOIL PHOSPHORUS AVAILABILITY TO SUBSEQUENT WHEAT CROPS IN THE BROWN SOIL ZONE OF SASKATCHEWAN
… vs. cereal stubble is due to differences in soil phosphorus (P) availability. The influence of pulse crops on soil P availability and P uptake by subsequent wheat (Triticumaestivum L.) crops was assessed in a series of laboratory experiments and field studies conducted in the Brown soil zone …

Soil phosphatase activity: sources of variability and relationships with phosphorus fractions
Soil phosphorus (P) is hypothesized to exist in pools varying in availability given that its availability is controlled by interacting soil geochemical and biological processes. Soil P pools have been widely characterized by sequentially extracting P from soils with increasing strength of …

Soil properties, lime and phosphorus fertiliser management affecting grass production in Ireland
… P fertiliser recommendations do not account for soil type differences, but large differences in fertiliser P responses can exist across differing soil types. The use of this one size fits all P fertiliser recommendation system can result in the depletion or over supply of P fertilisers compared …

Impacts of Fertilization on Soil Properties in Loblolly Pine Plantations in the Southeastern United States
… applications on the O horizon and mineral soil in loblolly pine (Pinus taeda L.) plantations over a 12-year period. To accomplish this, we used 9 experimental sites located across the south, which were grouped using the CRIFF Classification System. Group 1—CRIFF A, B (poorly-drained …
