Rainfall is one of climate elements that influence the spatial and temporal variation of plant cover in any region and, in particular, in the caatinga semiarid  Northeast. Before this, there was a need to examine relations of seasonal rainfall in the... see more

Precipitation is one of the main factors that explain production of biomass in grassland and shrubland. Precipitation use efficiency (PUE), the ratio between biomass production and precipitation, allows the use of simple modeling paradigms (Simple Ecologi... see more

In Mexico, the foraging-stock load in pastures is not regulated according to stocking rates, which are estimated in terms of coverage and productivity; this situation has led to the degradation of the vegetation coverage, the reduction of infiltration and... see more

Nitrogen (N) has commonly been applied in Eucalyptus stands in Brazil and it has a direct relation with biomass production and chlorophyll content. Foliar N concentrations are used to diagnose soil and plant fertility levels and to develop N fertilizer ap... see more

The BBCH scale is widely adopted throughout the world for the description of the growth stages of several economically important crops, but a detailed description of the stages of phenological growth in huizache (Acacia farnesiana (L.) Willd.) has never b... see more

The study devoted to problem of landslide dynamic in the territory of Dnipropetrovsk oblast. Study area covered right bank of Dnipro river, between Dnipro and Kamyanske cities. The territory characterized with hilly plain relief on loss soils. Specific co... see more

The present study aimed to evaluate the mutual dependence between the spectral behavior in the cotton canopy, the leaf area index and biomass production. The study took place, in field conditions, under irrigation, in the Busato I Farm in the city of São ... see more
