Microbiological evaluation of meadow chernozem carbonate soil under various fertiliser systems

Soil enzymatic characterization of different soil types under meadow

Studies to the feasibility to characterize soil types by soil microbiological and biochemical analysis focus on the existence of microbial and biochemical characteristics distinctive to individual soil types. Many authors have attempted to elucidate relationships between microbiological and physico-chemical properties of different soil types (DUTZLER-FRANZ, 1977a, b; KHAZIYEV and KHABIROV, 1983...

Soil solarization in various agricultural production systems

Soil solarization is a natural, hydrothermal process of disinfesting soil of plant pests that is accomplished through passive solar heating. Solarization occurs through a combination of physical, chemical, and biological mechanisms, and is compatible with many other disinfestation methods to provide integrated pest management. Commercially, it is used on a relatively small scale worldwide as a ...

Soil Degradation - I: Effect of Fertiliser Use on Penetrometer Resistance

A 58-yearold burning and trashing trial receiving fertiliser and no fertiliser was used to quantify treatment effects on soil penetrometer resistance. The results showedthat penetrometer resistance was significantly lowerin thosetreatments whereno fertiliser wasapplied. Increased soilwatercontentin treatments witha trashcoverdid notreducepenetrometer resistance values in the soil wherefertilise...

Agro-Industrial Waste Management: A Case Study of Soil Fauna Responses to the Use of Biowaste as Meadow Fertiliser in Galiza, Northwestern Spain

Microbiological quality of goat's milk obtained under different production systems.

In order to determine the safety of milk produced by smallholder dairy goat farms, a farm-based research study was conducted on commercial dairy goat farms to compare the microbiological quality of milk produced using 3 different types of dairy goat production systems (intensive, semi-intensive and extensive). A survey of dairy goat farms in and around Pretoria carried out by means of a questio...
