Abstract

The loss of soil, which constitutes one of the most important life supporting systems, results in lowering productivity and if unchecked may even threaten the very existence of life. Apart from reduction in productivity and destruction of valuable forests, it also reduces basin retention capacity causing floods in the down stream side and siltation of multipurpose reservoirs should be considered as non renewable and hence need to be protected on priority. It is therefore, essential to adopt proper conservation measures which are most effective and 1east expensive. Accordingly, studies were initiated since 1986, in two mine areas, namely (a) Navalutti Mines near Sandur (60 km from Bellary) under lease of M/s H.R.. Gaviappa & Co., and (b) Metriki Forest (Karnataka Forest Department). Vithalapuram Mine situated at 30 km on the south-west direction from Bellary.

Abstract

An experiment comprising of six treatments based on combination of three types and two times of mulching and four replications was conducted during 1967-1972 at the Soil Conservation Researeh Station, Vasad (Gujarat) to study their effect on comparative success and cost of afforestaion in a semi-arid ravinous tract. The results show that clod mulching (Soil hoeing without pulverisation and spreading clods on the surface in one meter diameter around plants) in post-monsoon period (October) gave significantly better height and diameter growth of khair (Acacia cateshu) plants as compared to grass mulching or the usual weeding and hoeing. Clod mulching in October also gave higher survival % of the plants and was overall cheaper in cost than the prevalent practice of weeding and hoeing.

Abstract

Various types of continuous, staggered contour trenches and pits were tried at Soil Conservation Research Farm. Vasad, for afforestation with Acacia arabica (Willd). Staggered contour trench of 3 m × 45 cm × 60 cm depth with raised mound of 1 m × 60 cm height (T4) was found to be the most suitable one giving mean height of 452.67 cm and diameter (collar), of 7.52 cm at the end of fourth year. It was followed by staggered contour trench of 3 m × 30 cm × 45 cm depth with raised mound of 1 m × 45 cm height (T3) and continuous contour trench of 30 cm × 45 cm depth with raised mound of 1 m × 30 cm height (T2)
