DIVERSITY OF SOIL MACRO FAUNA AND ITS ROLE ON SOIL FERTILITY IN MANGLID
AGROFORESTRY.
Soil macro fauna is one of the bio indicators in determining the quality of the land.
The total soil macro fauna is influenced by the climatice condition and land utilization pattern.
Agroforestry is one of type land utilization that is expected to improve the soil fertility.
Land utilization changing from monoculture into agroforestry is predicted to influence the soils macro fauna.
This study is aims to find out the population of soil macro fauna before and after applying manglid agroforestry.
The research was conducted in Cukangkawung.
Tasikmalaya District.
West Java Province.
Sample of macro fauna was taken from non-productive land of tea plantations and one year after the land was planted by manglid corn peanut by using agroforestry.
Samples were taken in Feb-March 2015 and once more in Feb-March 2016.
The observation land area is 1 hectare that is divided into 1 m x 1 m - 16 observation plots that was placed In each plot, a hole of 30 cm in depth was made and the dug out soil was placed on the plastic The collected macro fauna was counted and placed into a bottle that was filled with 70% alcohol.
The macro fauna identification was conducted in LIPI zoology laboratory.
The research shows that the diversity indexes for Shanon and Margalef on manglid agroforestry are higher than on the ex tea land.
Factors that influence the soil macro fauna diversity improvement is pH, low temperature of soil and high soil moisture.
Soil macro fauna becomes organic decomposer in agroforestry for about 56,25% and 20% in non-productive land of tea plants.

INTRODUCTION
Soil organism has an important role as chemical and ecosystem engineer, and biological regulator (Widyati, 2.
Soil macro fauna is one of soil organisms that have many types and Its existence is influenced by biotic and abiotic factors inside the soil (Dwiastuti.
The biotic factors are micro flora and plant species, while the abiotic factors are physical and chemical characteristic of soil.
The physical characteristic consists of soil structure and texture, while the soil chemical characteristic consists of pH, salinity, soil organic materials and minerals (Nurrohman.

Water inside the soil influences the number of nematodes.
However, the antagonist biotas are able to breed inside less water Ae soil (Swibama.

wrote that land management can increase or decrease the soil macro fauna population.
Agroforestry as land utilization pattern is applied by many farmers.
They expect gaining more income and harvesting products continuously by applying the agroforestry Farmers can choose it because it can guarantee and improve the food needs, quality of nutrition, and because of culturate factor (Tjatjo.

wrote that tree has canopy to protect soil from erosion, while root of tree will prevent the leaching the soil nutrients.
This can maintain the soil organic material, land fertility, and the numbers of soil Nowadays, there is a lot of tea garden with low productivity.
One of the causes is low soil It is because the biomass of tea leafs is imbalanced with the fertilizing activity.
The input of organic material into the land is less because of less litter produced by tea leafs.
Some farmers in Tasikmalaya change tea plants into seasonal plants or woods or agroforestry.
Manglid is one of the developed tree species in Tasikmalaya because manglid is suitable to the land condition .

utilization that is changed from tea garden monoculture into manglid agroforestry with seasonal plants gives effect on the number of population of soil macro fauna.
Agroforestry causes land utilization, organic and non-organic fertilization, and litter of main plant and harvesting product of seasonal plants.
Soil fauna is used as soil bio-indicator because it has a high respond to soil utilization, soil characteristic and climate (Swibama et al.
, 2.

Falco.
Sandler and Coviella .
wrote that macro fauna activity is influenced by climate, soil characteristic, and organic residue.
Macro fauna has a role in decomposing organic material where the residue is mineralized by the bacteria (Hilwan & Handayani, 2.
The research is aimed to compare the number of population of soil macro fauna before and after manglid agroforestry.
The comparison is aiming to determine the effect of agroforestry on soil biological fertility.

However, its index is lower than agroforestry of sengon and pineapple .
(Wulandari.
Sugiyanto, & Wiryanto, 2.
It is because agroforestry of manglid and seasonal plants is young, still one year since it was planted.
That makes the size of manglid tree is still small and land is covered by dominant seasonal plants.
Meanwhile the agroforestry between sengon and pineapple has been applied longer than on the manglid.

Correlation value of soil moisture between the diversity and wealth index of macro fauna species is positive.
Higher moisture of soil will make higher index of diversity and wealth of macro fauna species.
This is caused by the improvement of soil macro fauna activities that is caused by the soil moisture (Bio Intelligence Service (BIS), 2.
The organic fertilization and the litter of seasonal plants in manglid agroforestry increases the soil moisture.

wrote that soil moisture is a factor that give the highest influence for the improvement of worm population.
Therefore, more land canopy will increase macro fauna Macro Fauna as Detritivore on Soil Fertility Soil macro fauna is consisted of a huge number of different organisms that live on, in, and inside pores of soil surface.
Macro fauna is found within 60 Ae 80 cm depth of soil.
However most zoo mass is in the 0 Ae 30 cm of depth of humus (Bragina, 2.

25%) than the others.
Worm is the main component of soil macro fauna community in most ecosystems and most macro fauna biomass.
Worm has important function in organic material decomposition.
Worm eats and destroys litter and other parts of dead plants.
It improves soil nutritious cycle through a fast joining process from soil detrition into mineral soil.
Beside, its mucus can improve the activity of other beneficial soil microorganisms.
Then, organic production becomes a succeeded process.
Therefore, in short term period, the significant effect is a huge concentration of soil nutrition (N.

Soil insect is insect that temporary or permanently live inside the soil.
Insect has a function as a detritivore or an organism that can reorganize the available organic material for green plants, so it can return the soil fertility (Sari, 2.
Soil insect eats live or dead plant.
Insect can accelerate the decomposition of organic material.
Soil insect is highly dependent on availability of energy and source of food, such as organic materials and live biomass and all of them are related to carbon cycle inside the The availability of energy and soil nutrition can keep the existence of soil insect, and it will make the activity of soil insect in sustainable (Ruslan, 2.
Based on Table 1, detritivore insect on manglid agroforestry has more number than on exAetea garden area.
On manglid agroforestry land, number of vegetation and litter is also greater than on exAetea garden.
Therefore, there is more food for soil insects.
The availability of fauna can be a parameter of soil quality.
The soil fauna as bio-indicator of soil fertility must be in relatively abundant number (Ibrahim.

CONCLUSION
Transformation of land utilization from tea monoculture to manglid agroforestry and seasonal plants causes change in the population of soil macro fauna.
Manglid agroforestry pattern has higher value in Shannon Diversity Index and Margalef Wealth Index than the exAetea garden.
The influencing factors of the variety improvement of soil macro fauna is pH improvement, lower soil temperature, and higher soil moisture.
