Practice Name:

Reclamation of Brackish Soil

Details

Category	Soil Management
Scout	HBN
Ingredients	Dry leaves of piludi or tooth brush tree (Salvadora persica).
Details Of Innovation	Farmer uses the dry leaves of piludi or toothbrush tree (Salvadora persica) to decrease the salinity of the soil. Accumulation of soluble salts in the soil is known as salinization. This type of soil is also called white alkali by Americans and Solonchaks by Russians. Due to an increase in the salt concentration, the soil becomes very hard, its infiltration rate becomes less, and fertility also decreases. To decrease the concentration of such salts, the farmer mixes 20 to 25 baskets (one basket contains ten kilograms of leaves) dry leaves of toothbrush tree in one bigha (.25 acres approximately) of land. The field is plowed before the onset of monsoon during the Kharif season. After the monsoon sets, the leaves decay and provide organic matter to the soil. These leaves gradually decrease the salts present in the soil through leaching. Thus the soil is gradually made productive. Most of the farmers in this area have been following this method for over ten years and find it very effective in decreasing the salinity of the soil.

PAS 1	"High soil salinity and alkalinity have degraded about 8.5 million ha of once productive land in India. The severity of the problem is increasing, and several million ha of the canal irrigated areas in the arid and semi-arid regions of the country run the risk of being degraded. Increasing human and livestock pressures on available land necessitates protracted efforts to reclaim lands which are already degraded, and to prevent their further degradation. Providing vegetative cover to such lands with suitable woody and herbaceous species can put the these lands to optimal use and also increase the forest cover of the country. The Central Soil Salinity Research Institute, Karnal, has found that trees of the genus Prosopis or mesquite can be used for the afforestation of salt-affected lands. These trees are highly salt-tolerant and excellent biomass producers. The technology has been developed for their cultivation in problem areas. This paper deals with various aspects of Prosopis cultivation for the rehabilitation of salt-affected lands. The most widely cultivated species of Prosopis in the world are P. juliflora, P. alba, P. chilensis, P. cineraria, P. pallida and P. tamarugo." http://www.fao.org/3/ad321e/ad321e08.htm
PAS 2	"The main aim of the introduction of Prosopis juliflora was to reclaim the saline and alkaline soils and extending the utility as firewood. In spite of that Prosopis juliflora is used for the varied utility." - http://www.ijpab.com/form/2018%20Volume%206,%20issue%201/IJPAB-2018-6-1-1088-1092.pdf
PAS 3	"Castor Oil Cake is one of the most versatile natural manures. It is truly organic manure which enhances the fertility of the soil without causing any damage or decay. It is enriched with the three big elements vital and conducive to the proper growth of crops - Nitrogen, Phosphorus and Potassium." https://sites.google.com/site/sunrayinternational/products/castor-oil-cake
