Weil: Soil–plant Influences on Phosphate Rock Efficacy

of nutrients, especially phosphate rock (PR) in subSahara Africa (McClellan, 1989; Buresh et al., 1997). Affordable technologies are needed to allow smallholder farmers Substantial deposits of PR in many sub-Sahara Afrito effectively use the phosphate rocks (PRs) found in many African countries. A pot study was conducted in Tanzania using two PRs can countries are too low-grade to justify comme...

Combining effects of soil solarization and grafting on plant yield and soil-borne pathogens in cucumber

Combining effects of soil solarization and grafting on soilborne pathogens, plant height and yield in cucumber were compared in a greenhouse of Bati Akdeniz Agricultural Research Institute located in Antalya in 2008 fall season. The experiment was set in split plot design containing; 1, 2, 4 and 5 months soil solarization (MSS), and non-solarized control plots (NSC) on which grafted Maximus F1+...

Plant Litter and Soil Reflectance

The presence of plant litter on the soil surface influINTRODUCTION ences the flow of nutrients, carbon, water, and energy in Ecological Importance of Litter terrestrial ecosystems. Quantifying plant litter cover is Litter is senescent (or dead) plant material that gradually important for interpreting vegetated landscapes and for decomposes into soil. It is difficult to classify litter beevaluat...

Soil and Plant Nitrogen Availability

Soil conditions and plant growth'

Plants can respond to soil conditions in ways that can not readily be explained in terms of the ability of the roots to take up water and nutrients. Roots may sense difficult conditions in the soil and thence send inhibitory signals to the shoots which harden the plants against the consequences of a deteriorating or restrictive environment, especially if the plants' water supply is at risk. Gen...
