To effectively implement hedge planting:

• Step 1: Purchase saplings of selected tree species from a local nursery or grow saplings in separate on-farm nursery. If growing on-farm, saplings should be held-up with an upright support bamboo/wooden pole. Ideally, the farmer should begin exploring silvopasture tree species beginning with indigenous trees, such as acacias, and other local trees. It is worth considering a mixture of species, as well as mixed shallower and deeper rooted trees.
• Step 2: Once at a meter or over in height, transplant to pastures, surrounding each individual sapling with a wire mesh cage-tube or insert into five-centimetre diameter PVC pipe to protect from browsers. Plant at least ten to twenty meters apart, in either a random or uniform pattern. This is a matter of preference.
• Step 3: Once saplings are planted, only allow grazing livestock (cows, sheep, ducks, geese, chickens) in the silvopasture, avoiding browsers (goats, etc), which will strip, damage or destroy the saplings.
• Step 4: Once mature and above browsing height, two plus meters, remove protective cage or pipe.
• Step 5: Depending on species, pruning, coppicing etc should be performed every two months to ensure that trees remain healthy and productive, while maximising outputs for in-field and cut and carry fodder.

To effectively implement SRI practices:

• Step 1: Consider separation of high-quality seeds from low-quality seeds through soaking them in plain or salt water and the unviable seeds will float on the surface of the water.
• Step 2: Plant the seeds on an unflooded, raised bed with adequate drainage and fertile soil.
• Step 3: After 8-12 days, transplant single young seedlings into a grind pattern with wide spacing between hills (25 cm x 25 cm).
• Step 4: During crop growth period, control the flooding and research and follow alternate wetting and drying irrigation practices.
• Step 5: Consider application of compost and mineral fertiliser for nutrient enhancement.
• Step 6: Use a mechanical weeder for the control of weeds and maximisation of soil aeration.

To effectively implement Alternate Wetting and Drying practices:

• Step 1: Alternate wetting and drying should be considered by the farmer after two weeks of rice transplant.
• Step 2: The farmer should consider digging half of 30 cm tube into soil to monitor water level.
• Step 3: When the water level is 15 cm below the soil surface the field should be irrigated again with a depth of 3 to 5 cm before water drains.
• Step 4: This cycle should be repeated until flowering stage to avoid disturbing reproduction because at this stage the crops are sensitive to water stress.

To effectively implement Rainwater Harvesting practices:

• Step 1: Create a water collection zone connected to a gutter system.
• Step 2: Install filters to the water collection zone.
• Step 3: Connect a hose pipe for easy distribution of irrigation water.
• Step 4: If a farmer intends to use water for human consumption other than flushing toilets, etc, water quality must be frequently tested using reliable and low-cost/low-tech solutions.
• Step 5: Use of filters can be considered to reduce particulate and other pollutants but should be thoroughly investigated – as a separate subject – by the extension officer and the farmer, otherwise it could lead to illness. It is recommended that farms utilise harvested rainwater for irrigation and other farming activities only.

To effectively implement Permeable Rock Dam practices, the following steps should be carried out:

• Step 1: Consider constructing a permeable rock dam across relatively wide and shallow valleys.
• Step 2: Permeable rock dams should consist of long, low rock walls with level crest along full length although farmers should consider central spillways where water course has cracks.
• Step 3: The dam should be between 50-300m in length and 1m in height within a gully.
• Step 4: Consider making the dam wall flatter on the downslope side than on the upslope side.
• Step 5: A foundation of small stones should be set in the trench.
• Step 6: An apron of large rocks is essential to split the erosive force of the overflow.
• Step 7: Downstream banks of the water stream should be shielded by stone pitching to prohibit the increase of the gully.

To effectively Water Spreading Bunds the following should be carried out:

• Step 1: Farmers should consider making earth bunds by hand, animal ploughs or mechanised ploughs.
• Step 2: Contour bunds:
  • Contour lines must be plotted and marked prior to developing the bund.
  • A 40 cm deep infiltration pit is dug directly above where the bund will be plotted.
  • Bunds should be spread 5 m to 10 m apart.
  • Material from the infiltration pit will be piled and compacted to form a 25 cm to 30 cm in height with a base of 75 cm.
  • Soil is piled to form a ridge along the contour. The more significant the slope, the closer the bunds must be plotted.
• Step 3: Semi-circle bunds:
  • Contour lines must be plotted and marked prior to developing the bund.
  • A centre point is chosen as diameter for the bund is selected (this could be 3 m or 30 m depending on the available space). From the centre point a string is used to stake out an even semi-circle.
  • Excavate a small trench before the bund and pile the excavated material. Pile and compact a bund wall, wetting it often to form the wall.
• Step 4: Contour stone bunds:
  • Developed on less steep slopes.
  • Must have access to local stones.
  • Dig out a shallow ditch, 10 cm to 15 cm in depth.
  • Lay largest stones at the bottom of the ditch and pile smaller stone upward.
  • Step 5: Regular monitoring of bunds should take place, especially after rain events or after significant periods of time. Repairs should be done if any damage is found.

To effectively implement Half-moon techniques, the following steps should be carried out:

• Step 1: Farmers should consider the diameter of the half-moon  between 2 m – 3 m, with a total surface area of approximately 1.5 sqm and 3.5 sqm.
• Step 2: Pits should be dug to a depth of between 15 cm to 30 cm.
• Step 3: Excavated material can be piled around the curved section of the half-moon.
• Step 4: The curved section of the half-moon can be reinforced by stones to prevent washouts of the half-moon.
• Step 5: 35 kg of organic fertilisers/compost should be evenly distributed in the half-moon.

To effectively implement Zai Pits the following should be carried out:

• Step 1: Zai pits should be dug with a diameter of 30 cm to 40 cm and 10 cm to 15 cm deep. 
• Step 2: Pits should be spaced 70 cm to 80 cm apart resulting in approximately 10,000 pits per hectare.
• Step 3: The farmer should place 2 – 3 handfuls (200 g to 600 g) of organic fertilisers or compost in each pit.
• Step 4: Holes that are dug between planting seasons will trap wind eroded soils, which are fertile and form good soils for plating crops.
• Step 5: It is recommended that 3 tonnes of fertiliser/compost per hectare be available.
• Step 6: Farmers should consider planting crops in these pits prior to periods of rain.
• Step 7: Repeated application of Zai pit technology on an annual basis will increase productivity of degraded land in the long term.

To effectively In Field Water Harvesting techniques, the following steps should be carried out:

• Step 1: Land is cleared, berms are developed, and crops are planted in order to direct water to the infiltration point.
• Step 2: The catchment areas should be sloped no more than 5 % and the area should be cleared to promote catchment as much as possible.
• Step 3: The infiltration pit (where water is stored) should be dug at the lowest point of the catchment areas and line infiltration pits with plastic or concrete roofing to limit water loss, and can be used as a source of irrigation for fruit trees and other high value crops.
• Step 4: Paths can be built of soil to guide water to the infiltration pit.
• Step 5: Alley cropping, or strop cropping can be used, with areas between trees and crops dug deeper like a trough to direct water to the infiltration pit.
• Step 6: To access water from infiltration pits, farmers can introduce a pumping system and water can be distributed around the farm as necessary

To effectively implement drip irrigation:

• Step 1: A reliable water source must be available - natural (natural or through rain-water harvesting).
• Step 2: Acquire a pump system (approximately $US 100) that maintains enough pressure to deliver water through the system or an elevated tank.
• Step 3: Connect lines or hoses and laterals that run from the pump system across the planted fields.
• Step 4: Run lines or hoses with emitters (drippers) or small punctures at the surface level along planted crops or just below the surface providing water to the roots system of the plants.
• Step 5: Once the system is operable, the pump can be turned on and water dispersed as required by the nature of the crop and can also be implemented with supplemental irrigation strategies (Technical Brief 23).
• Step 6: Monitor the irrigation system regularly to ensure there are no malfunctions and the system is maintained. Crops that receive regular water can develop shallow root systems and any prolonged disruptions in service could have   significant impacts.
• Step 7: If applying drip irrigation in sloped conditions, follow the contours of the slope as outlined in Technical Brief 16.

Once a drip irrigation system is up and running, farmers can explore fertigation, the addition of soluble fertilisers into the irrigation system water for distribution directly to plants.
