Relationship between aboveground dry weight and N, P and K concentrations in grassland species: A guaboveground dry weight and N content. The N dilution in the dry matter could be described by only one equation for all species (N = 6 × Y.). The differences between species for P were very small, but . was always richer than the grasses in K and Mg. The sorting out of the forage samples are thus nec

Nutritional disorders between potassium, magnesium, calcium, and phosphorus in soiltration of cations was governed by the amount of soluble anions and the proportion between the different cations was dependent on exchange reactions and is described by activity ratio. High activity ratio between potassium and calcium induced Ca-deficiency, which resulted in a restricted root functi

The use as fertilizer of combined primary/secondary pulp-mill sludgeined primary / secondary pulp-mill sludge to that crop, as well as to study its effect on physical and chemical characteristics of the soil. From the results obtained no yield reduction was observed, in contrast with the results obtained from studies undertaken with the primary sludge, where amounts

The use of industrial wastes as manures: A case study with effluent mud from an olive oil processingns of maize were studied. Nitrogen enriched EM applications improved the yield and lowered toxic element and sodium concentrations. Excluding the lowest rate of EM, all tested effluent doses resulted in poor growth.
