Make Terraced to grow trees
Ngày đăng: 18/05/2017Lượt xem: 1152On the slopes, On the slopes,cultivation by conventional techniques (slash burning, plowing then sowing) make soil and fertilizer easily washed away.Creating Terraced aimed at sowing helps to prevent soil from being eroded and washing away; and increase fertilizer use efficiency.The technical package: Use A square ruler to design Terraced according to intermediate contour lines, starting from the bottom of the slope. The distance and width of Terraced depend on the slope of fields, and crop types. The steeper the slope of a field is, the wider the distances between Terraced are. The surface of the ladder should be large enough to plant a row of trees. It is possible to combine Terraced and land cover by retaining the entire plant body to cover Terraced surface instead of burning field
The benefits of applying this technical package include:
- Reducing soil erosion and reduce soil organic fertilizer washout; thus, contributing to reducing greenhouse gas emissions;
- Gradually improving the structure and fertility of the soil, enabling plants to be healthy and adapt better to weather changes.
- Increasing the efficiency of fertilizer use and raising productivity and income of farmers in the long run.
- When combined with land cover application by plant residues or intercropping, it can produce additional effects of intercropping and land cover (Le Quoc Doanh and collaborators, 2005; Oleg Nicetic and collaborators, 2011).
The Terraced may be applied in conjunction with land cover application and / or intercropping; Then the impact of the practices is resonant (Le Quoc Doanh and collaborators, 2005, Oleg Nicetic and collaborators, 2011).
This practice was originally designed and recommended for corn on sloping land. However, due to the need of more labor for the Terraced, it was not adopted by farmers growing corn. In fact, the application is limited to the experimental framework of a number of projects.
However, the Terraced is applied to some other crops, such as tea, coffee and rubber. Due to labor costs, the Terraced are often not designed as recommended, such as the smaller the ladder surface, the greater the distance between the steps.
In the case of rubber, tea and coffee, some projects are now supporting farmers for creating ladders for planting on steep slopes.
The main obstacle in expanding the Terraced application is the high demand for labor to create the Terraceds in the first year (Oleg Nicetic and collaborators, 2011) and the required labor to maintain and stabilize ladders in subsequent years.Figure 1: Creating the Terraced for corn cultivationTable 1.
