Optimum Use of Marginal Land with Sgroforestry System


Figure

Private marginal lands, such as abandoned terraces, degraded and/or eroded land and often single-cropped areas, can be converted into more productive land.

While establishing the system, the emphasis must first be given to improving the soil fertility of the land. This can be done through the use of legumes (green manuring), in situ mulching and/or composting and the incorporation of any other locally available organic matters, such as agricultural by-products and other bigdegradable materials.

BENEFITS ACCRUING FROM THIS SYSTEM

1. Productive use of marginal land.
2. Reduction of soil erosion.
3. Early returns as fruit, fodder grass, vegetables and fuelwood can be harvested the second year.
4. Income-generating sources created.
5. Lower maintenance because perennials require less attention than annual crops.

FACTORS TO BE CONSIDERED BEFORE ESTABLISHING THE AGROFORESTRY SYSTEM

1. Identify the marginal land to be converted.

2. List the locally available and suitable plant species. These will include legumes, shrubs, fruit and other multipurposes trees selected by the farmer.

3. Protect the area, if necessary, through live fencing, using plants, such as Asuro, Khirro, Taleto, Padke, Simal, Ketuki, Sajiwan, Sihundi, Nilkanda, etc. Stone-fencing can be built if sufficient stones are available.

4. Prepare a simple scheme of tile major species that the farmer wants to establish over the long term. Focus should be given to fruits and fodder.

5. In-situ composting, green manuring and green leaf manuring should be done wherever possible for improvement of soil fertility and for water conservation.

STEPS TO BE TAKEN WHILE ESTABLISHING THE AGROFORESTRY SYSTEM

1. Seasonal legumes with vigorous growth, for example: cowpea, velvet bean and rice bean (masyang) should be planted in the beginning in order to have enough soil cover, thereby improving the soil condition. Planting should be dense and thick. The best time to plant these species is April-May.

2. In the first year, with the onset of the monsoon, pioneer species, such as banana (at lower elevations), pineapple and some tree species can be planted following the contour or at regular intervals. At the same time, pits can be dug for other tree species.

3. The dug soil from the pit should be mixed with a little compost and returned to the pit in order to prevent soil loss.

4. Tree seedlings can be planted in the prepared pits during July-August.

5. The base of the fruit and other tree seedlings should be mulched in order to prevent soil moisture loss and to provide nutrients from the organic matter to the seedlings.

6. Weed the base of the tree regularly.

INTERVENTION SCHEME


INPUTS/ACTIVITIES

OUTPUT/RETURN

I

· Planting grain legumes, banana, pineapple, up to 100 m aft. and some tree species
· In-situ compost-making
· Addition of all available organic matters
· Mulching and weeding

· Seasonal legumes can be harvested
· Fodder grass for cattle can be harvested

II

· Continuation of legumes and in-situ composting
· Planting fruit saplings
· Replacement planting, if necessary
· Planting of vegetables (i.e., brinjal, tomato, pumpkin, gourd, etc.)
· Continue mulching and weeding
· Addition of more tree

· Seasonal legumes and early -maturing pineapples can be harvested
· Grass, fodder can be harvested

III

· Continue activities, such as legume planting, mulching and weeding at the base of fruit trees


AN EXAMPLE OF USING MARGINAL LAND FOR INTEGRATED FRUIT FARMING

· Establish a diversified fruit orchard integrating mandarin orange, sweet orange, lemon, coffee, cardamom, guava, pineapple, banana, plums, pear.

· Plant ipil-ipil and Albezzia falcataria on the band of terrace by direct sowing. Distance between plants should be 50 cm.

· Plant sisso, bakaino, neem, bamboo, koiralo and other fodder species on the boundary line of the orchard with the following distance between plants:

· Sisso - 2.5 m.
· Bakaino - 10 m.
· Neem - 15 m.
· Bamboo - 30 m.

· Fodder trees in between of other plants.

· Plant coffee, banana, orange and pineapple. Alternate orange and coffe in rows. Plant banana and pineapple throughout the fields between the orange and coffee.

· Intercrop various species of legumes, garlic and onion.
