Balanço do nitrogênio (15N) da uréia nos componentes de uma pastagem de capim-marandu sob recuperação em diferentes épocas de calagem Urea 15N balance in the fractions of a Brachiaria brizantha cv. Marandu pasture under recovery with different liming dates

Revista Brasileira de Zootecnia, 2007
Com o objetivo de avaliar a fertilização nitrogenada com uréia, realizou-se um experimento com duas formas de aplicação de uréia (incorporada ou em superfície) e com calagem em duas épocas (março e agosto), para balanço do nitrogênio (15N) em pastagens ...

Synergistic Effects of Subsoil Calcium in Conjunction with Nitrogen on the Root Growth and Yields of Maize and Soybeans in a Tropical Cropping System

Agronomy, 2023
A large part of Brazilian maize is double-cropped after soybeans, when water shortages are very frequent. A larger root system can mitigate drought stress and enable better nitrogen (N) use.

Boron Leaching Decreases withIncreases on Soil pH

Revista Brasileira de Ciência do Solo, 2016
Management of boron fertilization depends on the magnitude of B leaching in the soil profile, which varies proportionally with the concentration of B in the soil solution, which, in turn, decreases as the soil pH increases due to the higher sorption of B

Growth Responses of External Hyphae of Arbuscular Mycorrhizal Fungi to Acidic Soil Conditions and their Effects on Cowpea Growth

Microbiology Indonesia, 2010
The effectiveness of arbuscular mycorrhizal (AM) fungi has often been attributed to growth of their external hyphae, whilst the hyphae themselves may be subjected to the effects of severe soil conditions.

Water-extractable alkalinity to estimate the acid-neutralising capacity of organic amendments

Geoderma
The effectiveness of amendments to increase the pH of an acidic soil can be expressed as acid-neutralizing capacity (ANC). The alkalinity measurement method, based on prolonged hydrolysis of organic amendments with acid, is widely used but may ...

Effect of cattle manure and dolomite on soil properties and plant growth in acid upland soils [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2005
One of the major plant growth limiting factors has been associated with soil acidity. In general, lime is used for pH raising in acid soils. However, it is also well known that manure can be used for acid soil reclamation for a better cultivation.
