Abstract

The used of zeolite mineral as soil ameliorant on agricultural had been known since long time ago. Cation exchange capacity (CEC) of zeolite is ≥ 100 cmol(+) kg-1 which regulated on SNI No 13-3494 1994 is a determining quality of zeolite test. However, it is very reasonable to be revised. There are several reason why determining CEC of zeolite on SNI No 13- 3494-1994 must to be revised, because there is an error as possible as on determining CEC of soil. The research aimed to study the measurement of CEC zeolite for agricultural which conducted on five laboratories were (1) Bogor Agricultural University by using stirring (shaking)-sentrifusi decantation methods, (2) Service Soil Laboratory at Indonesian Soil Research Institute by using percolation method that measured by calorimetric auto analyzer, (3) Soil Laboratory at Indonesian Soil Research Institute by using percolation method that measured by spectrometry, (4) PT. Sucofindo, and (5) Research and Development Centre for Mineral and Coal Technology by using percolation method. The result from quality test of CEC zeolite A and zeolite B from five laboratories was significant different, because the difference procedures of the method such as zeolite quality (grade and types), zeolite fineness, and ratio of zeolite to ammonium acetate solution. The criteria of CEC zeolite for agricultural on SNI recommended to be revised on five types are (1) ≥ 100 cmol(+) kg-1(class A); 100 - 80 cmol(+) kg-1 (class B); 80 – 60 cmol(+) kg-1 (class C), 60 – 40 cmol(+) kg-1 (class D), < 40 cmol(+) kg-1 (class E). The result from test of zeolite effectiveness on green house condition showed that distributing of zeolite soil ameliorant could improving grain yield pithy about 19,41% with the average weight of grain pithy with zeolite are 73,30 gram/pot, while without zeolite are 61,22 gram/pot. Giving the combination of ZKK with manure increasing higher the dry weight loose maize is 8,44 tons/ha than without giving the ZKK is 5,65 tons/ha.

Abstract

Improving the quality of soils degradation can be achieved using the soil ameloirant (i. e. Zeolite, manure, compost, etc.), conservation farming systems, organic management, system balanced fertilization specific location, and efficiency of water use. This study aimed to determine: (1) the type of soil ameloirant that is still used by farmers, sources of information, and its use of doses, (2) constraints and benefit of use, (3) fertilizer efficiency, and (4) development opportunities. This study conducted by survey method that is structured interview included: farmer characteristics, identification, and soil ameloirant development prospects in the future. Identification of soil ameloirant, such as: type of soil ameloirant used by farmers, sources of information, applications, the impact of the use, benefits and constraints of use. The results showed that: the distribution age of respondent ≤ 55 years (80.7%) and > 55 years (19.3%). Dissemination through counseling, pilot project on farmers land in order to developing the confidence of farmers will benefit and importance of the use soil ameloirant to repair land degradation, increasing productivity, and agricultural production. The soil ameloirant have been used by 24% of respondents farmers is zeolite granules (Agro-88) and dolomite; measurement of soil ameloirant for rice field: 500 kg of zeolit /ha and 577 kg dolomite/ha; garden: 219 kg zeolite/ha and 409 kg dolomite/ ha; mixedgarden: 600 kg of zeolit/ha and 143 kg dolomite/ha. Soil ameloirant benefits is for increasing the production: paddys, corns, and vegetables (cauliflower, peppers, tomatoes) around 10-30%, improving the soil fertility and reducing dosage of urea fertilizer as much as 15-30% and SP-36 as much as 30%.
