Module 6.7 Species Selection – Altitude, Temperature, Rainfall, Soil Depth, Community needs Session – III Time: 10:00 am to 12.00 noon By: SI partners Objectives • Overview of the last session • Topography, temperature and rainfall of Meghalaya • 5W1H Framework for implementation of Agroforestry • Soil properties • Species selection Overview of last session • Understanding fundamentals of Agroforestry system. • Different Agro-forestry systems • Case studies from Meghalaya Region reflecting the monetary benefits of these systems • Why agro-forestry and SDM are interlinked • The two questions that were to be answered in this session: – How do we counteract the acidic nature of soil due to pines – Can we promote local species for agro-forestry systems Tropic Zones Altitude of Meghalaya Meghalaya has a temperate climate with the low to high altitudes affecting the climate Rainfall of Meghalaya The average annual rainfall is 2600mm over western Meghalaya, 2500 to 3000 mm over northern and about 4000mm over south-eastern Soil Properties Rich in: Organic Carbon (Nitrogen supplying potential of soil) Deficit In: Phosphorous & Potassium Soil Properties-Common Soil Types in Meghalaya – Red Loamy or hill soils – Lateritic soils – Alluvial soils Soil Properties Location Agricultural Use •Derived directly from residuary base and intermediate Red Loam Central upland igneous rocks by weathering hot climates Not very useful for or hill soil of Khasi- •Deficient in potash, phosporic acid and lime agriculture Jaintia Hills •The soil is mostly sandy because of sanstone •Formed by weathering of rocks like granite, gneisses, The western diorites. part of the Paddy, potato, fruits, •Deficient in lime, potash, iron oxide, phosphorous, central Laterite and other crops in nitrogen and humus uplands, and plains and terraces •It is sandy in southern War country, silty loam on flat western section valleys, loam to silty loam ins western Garo hills of Garo hills Periphery of •Deficient in nitrogen, humus and phosphorous but rich in Suitable for Meghalaya: Alluvial potash and lime cultivation of rice, Garo, Khasi & •Vary in nature from sandy loam to clay fruits and vegetables Ri-bhoi hills 5W 1H of Agroforestry A 5W 1H framework can guide us implement Agroforestry System in an area: • What is our understanding about Agro-forestry? • Why to plant, (benefits of Agroforestry+SDM)? Covered • Where to plant (Selection of Site)? • Which tree species to plant (Selection of Plants/Mixing combination) ? This Session • Who needs own the process (Stressing Community onus)? • How to plant (Incorporating the Nursery techniques)? Next Next Session Where to Plant (Site Selection)? Considerations in selection of Site: • Location: Ensure ease of transportation to the location of final plantation. Also, has to be on a previous forest land rather than agricultural sites. • Water Availability: Enough water available during dry season. A nautral source of water at a higher level from which water can be tapped using gravity • Topography and drainage: The site should be almost flat with good drainage. Should be selected close to the edge of a high forest or in the middle of a grassland • Soil: Ideally should have sandy loam to loamy texture. Soil should have a pH 5.5 to 7.5, moderate fertility, with a minimum of 2.5% organic matter.
