There are several ways to fertilize tanah.diantaranya:
In clay-rich soils (clay).
This type of soil contains a lot of food but unfortunately can not be eaten by the plant due to insufficient blood levels of oxygen (O2). To overcome that is sought to be provided O2. The trick is to provide: compost, charcoal Bokashi manure, or other organic materials to the soil became loose.
On the sandy soil or soil that contains a lot of sand.
This soil type is difficult to bind with water, dries quickly and languish. As for how to resolve this soil is to add organic matter such as compost, Bokashi manure, organic fertilizer green leaves perishables coupled with manure, soil and water at a ratio of 1: 1: 1: 1, store in the drum and let it sit for 3 weeks.
On the lime-rich soils.
This soil type has high acidity, erosive, micro food less available (eg, iron, zinc, copper). To solve this type of land like this is to provide compost and green dedaunanyang especially when the leaves flowering plant species of butterflies such as nuts, Venus, Turi, etc. And to lower the acidity level is done by providing fertilizers containing sulfur.
Acidic soil.
Signs of soil that is acidic when in the fields of water color yellow rusty, when on the ground like overgrown weeds, haredong (Sunda) / sedudu, when planted with corn and yellow corn fruit when planted peanuts berenas no fruit. When they find this soil acidity (pH) ranging between 3 - 5. Thus the pH should be adjusted in advance in accordance with the wishes of the plant. To resolve this issue ground as there are many ways among which:
Dried soil.
Soil dug, plowed. Land in the form of chunks left bronzed by the sun for two weeks.
Given the husk.
Sprinkled soil dug up next rice husk charcoal mixed with the soil.
Improving the system of air in the soil.
The soil is then ditches to avoid the puddles and on peat soil made extending to a distance of 25 m to enable the leaching and acid flowing.
Adding organic fertilizer.
By adding organic fertilizer derived from animal waste that much, then gradually pH of the soil will be gradually increased, or in other words the acidity is reduced gradually.
Liming.
To lower the level of acidity or pH increase agricultural lime can be sprinkled on the ground that has been dug and then dug up and then mixed with the soil, when agricultural lime was mixed with ground water can also flush with rainwater premises, allow 10 to 15 days, newly planted. To increase the amount of lime can be done by the following calculation: If the soil pH is known us 4.5. Soil pH we want 6, then 6 - 4.5 = 1.5. Then we are on the table-1. Requirements Table Lime Dolomite at pH 1.5, the difference is obtained administration of agricultural lime 5:25 tons / ha. Further addition can be done again after 3-5 years. Just do it . . Lets go . .
