Appropriate technology to solve environmental problems due to chemical fertilizer ( an-organic) and water ( flooding) is to make a drill or Portugal Lobang Resapan Biopori. Tool with dimensions 1 m, made of metal and drill steel.

As known, fertilizing plants using prill fertilizer by farmers is often excessively long compared to the dose recommendations, fertilizer scattered and far from the tree root, and the mouth of the stream carried fertilizer ( leaching top run-off) and evaporates the heat carried away. Plant roots around hard, too often there is a puddle of water due to poor drainage or garden plantation in the area below the surface of the river water. Puddle of water in large scale can also occur due to high rainfall is not accompanied by the land' s ability to absorb and trap the water because of the limited aperture of catchment. Land is too long diasupi chemical fertilizer and the land around urban areas and buildings will generally be difficult to absorb rain water.

Benefits Biopori hole is to increase water absorption power, increasing the role of soil fauna activity and the roots of plants and water problems due to flooding and poor drainage.

How to Making Holes

1. Make a hole using a drill or Biopori Portugal into the soil that is cylindrical with a diameter of 10 cm, depth 100 cm and the distance between holes 50 to 100 cm,

2. Mouth hole reinforced mortar width 2 to 3 cm, 2 cm thick around the hole,

3. Fill holes with compost of half-baked ( still warm and the decomposition proceeds by microbial activator)

Within 7 days to 1 month breeding will occur in the soil micro-organism, thus making the soil crumbs and merongga and would extend all of the holes catchment. With peronggaan and penderaian land, Lobang be able to accommodate and trap stagnant water ( rain) exceeds the original volume ( diameter x height aperture) when first created.

The number of holes adapted to the intensity of absorption of rain water into the soil will be trapped. For example, the intensity of rain 50 mm / h ( rain) water permeation rate per hole 3 liters / minute ( 180 liters per hour) on 100 m2 of land, need to be made ( 50 x 100) divided by 180 or as many as 28 holes Resapan.

Portugal drill is also useful to overcome problems in the application of fertilizer ( tablets) . This is simply making holes in a way sowing soil around the tree. Make a hole up to 15 cm from the ground some 4 to 8 holes - the eighth in the direction of the wind. Put the tablets in accordance Gramalet recommended dose. Close the hole with soil, clean the weeds around the roots + + )
