| Declining soil fertility is a challenge to sustainable agricultural production in sub-Saharan Africa with a case of Uganda. However, the large volumes of agricultural waste generated from pineapples can be converted into soil conditioners through vermicomposting. by the use of earthworms. Several types of agricultural waste have been studied extensively as vermicompost feedstock, but little work exists on pineapple waste. The objective of this study was to investigate the suitability of pineapple waste for vermicomposting. To achieve this, an assessment of the physicochemical properties of fresh, pre-composted pineapple waste, and the resultant vermicompost, and determination of the optimal feeding rate and stocking density were performed. The study... |

| The effect of levels of polymaleic acid was studied on the structural stability of two saline soils exposed to intensive cultivation. Soil samples with undisturbed structure were collected and placed in containers where levels polymaleic acid (0, 10, 20 and 30L/ha) were applied diluted water, in order to raise the moisture up to field capacity. One week later, controlled drip irrigation was applied using a volume corresponding to the pluviometric precipitation of the areas where the samples were collected. The washed soil samples were taken from the containers with the objective of lowering the moisture and separating the aggregates, considering those which passed through a 4 mm sieve and were retained in a 2 mm sieve. From each soil type, four bags of... |

| ABSTRACT This study was conducted to evaluate the chemical effects of gypsum on the soil and on the recovery of a pasture established with palisade grass (Urochloa brizantha) in a Cerrado biome region. A randomized block experimental design with six treatments and four replications was adopted. Treatments consisted of five levels of gypsum (0, 450, 900, 1800, and 3600 kg ha−1) plus an unmanaged control treatment (without gypsum or additional chemical fertilizers). The gypsum treatments received addition of fertilizer (200 and 40 kg ha−1 of N and P respectively). The soil treatment started in October 2012. The application of gypsum provided an increase in plant height, number of tillers, and dry matter of the shoots of palisade grass. Gypsum combined with... |
