Tree seedlings respond to both light and soil nutrients in a Patagonian evergreendeciduous forest
(Public Library Science, 2017)
Seedlings of co-occurring species vary in their response to resource availability and this has implications for the conservation and management of forests. Differential shade-tolerance is thought to influence seedling ...
Identifying sulfur deficient fields by using sulfur content; N: S ratio and nutrient stoichiometric relationships in soybean seeds
(Elsevier Science, 2012-08)
Sulfur (S) fertilization has increasingly become an important issue in crop management. In Argentina S deficiencies have been reported, but there has been no success in finding soil tests for predicting soybean response ...
Prey C:P ratio and phosphorus recycling by a planktivorous fish: advantages of fish selection towards pelagic cladocerans
Prey selection by the small planktivore Galaxias maculatus and phosphorus gain depending on diet has been examined related to predator–prey daily distribution. Prey elemental composition (C:P ratio) was analysed as a factor ...
Nitrogen And Potassium Fertilization In A Guava Orchard Evaluated For Five Cycles: Effects On The Plant And On Production
(Revista Brasileira de Ciencia do Solo, 2016)
Balancing guava nutrition with liming and fertilization
(Sociedade Brasileira de Fruticultura, 2012-12-01)
A resposta da goiabeira à calagem e à adubação pode ser monitorada por análises de tecido vegetal. O perfil nutricional é definido em relação a padrões de teores de nutrientes. No entanto, os teores de nutrientes-padrão ...
Nutrient accumulation in 'Fantasy' net melon cultivated on substrate
Knowledge of the most essential nutrients for plant growth facilitates the efficient handling of its nutrition, especially when they are grown on a substrate supported by fertigation. The objective of this study was to ...
Compositional nutrient diagnosis of corn using the Mahalanobis distance as nutrient imbalance index
(Agricultural Inst Canada, 2014)
Calcium: magnesium ratio in amendments of soil acidity: nutrition and initial development of corn plants in a Humic Alic Cambisol
(UNIV ESTADUAL LONDRINA, 2008)
The variation in the Ca:Mg ratio in amendments used to neutralize soil acidity is one way of altering the availability of those nutrients to the plants in acid soils. The objective of the work was to evaluate the effect ...
