“…During the decomposition process of organic matter, nutrients are released, including base cations (Cai et al, 2019). In addition, rock phosphate also contains elements of Ca and Mg (Kasno & Sutriadi, 2012); when P elements are released, Ca and Mg elements are also released. An increase in the elements of Ca and Mg will be followed by a decrease in Na, evidenced by the decreasing ESP value.…”

Agricultural constraints on sandy soil are poor chemical characteristics and low biological activity resulting in the soil becoming less productive to be planted. One of the efforts to improve the quality of sandy soil are application of mycorrhizae and a soil ameliorant. The purpose of this study was to determine the effect of mycorrhizae and a soil ameliorant on soil chemical characteristics and soil biological activity. The experiment was arranged using a Complete Randomized Design that had two factors. The first factor (1) was mycorrhizae dose, without mycorrhizae (M0) and six spores of mycorrhizae/plant (M1), and the second factor (2) was types of soil ameliorant, without ameliorant (S0), cow dung (S1), rock phosphate (S2), biochar (S3), cow dung–rock phosphate (S4), cow dung–biochar (S5), and rock phosphate–biochar (S6). The results indicated that combination of six spores mycorrhizae/plant–cow dung 60 tons ha−1–biochar 25 tons ha−1 (M1S5) increased soil organic carbon (SOC) (235%), available P (675%), cation exchange capacity (CEC) (216%), total glomalin (101%), and easily extracted glomalin (69%), decreased exchangeable sodium percentage (66%), and increased absolutely for root infection and spore density than without mycorrhizae and a soil ameliorant (control). The lowest of SOC in non-mycorrhizae and rock phosphate, available P, CEC, root infection, spore density were found on the control, but the lowest of total glomalin and easily extracted glomalin were found on non-mycorrhizae–rock phosphate. The application of mycorrhizae, cow dung, and biochar improved the sandy soil characteristics.

Source of P fertilizer which is used by farmers in upland acid soils area is generally acidulated phosphate rock (PR), such as tripel super phosphate (TSP), super phosphate 36% P2O5 (SP-36), as well as partial acidulated phosphate rock (PAPR) which contain 10-30% P2O5. Their effectiveness, however, varies and depends on the soil and plant types. Phosphate rock fertilizers have a high prospects for acid soils because its effectiveness equals to the SP-36, cheaper, slow release, and its application can also leave the residual P in the soil that available for plants for next few seasons. Field experiment aimed to study the effectiveness of direct application of PR at upland acid soils and its effect on soil available-P as well as maize (Zea mays L.) yield was conducted in Acid Inceptisols of Ciampea, Bogor in wet season years 2008/2009. The experiment was arranged by a Randomized Completely Block Design with 3 replications. Maize of P-12 variety was used as a plant indicator. The treatment consisted of 6 levels of phosphate rock: 0, 20, 30, 40, 50, and 60 kg P ha-1, as well as one level of SP-36 40 kg P ha-1 as standard fertilizer. In addition, urea of 300 kg ha-1 and KCl of 100 kg ha-1 were used as basal fertilization. The result showed that the application of PR in the amount ranging from 20 to 60 kg P ha-1 increased total-P and available-P, and pH, decreased exchangeable Al in the soils as well as increased maize straw and grain. Phosphate rock application at 40 kg P ha-1 level was equally effective as SP-36 in the tested soils. Critical level of soil P for maize grown in the soil was 675 and 5.00 mg P2O5 kg-1 extracted with HCl 25% and Bray I, respectively. The requirement of P for maize grown in the soil to achieve maximum profit was 38 kg P ha-1 and 17.5 kg P ha-1 or equivalent to PR of 583 and 268 kg ha-1 in low (soil P < critical level) and high (soil P > critical level) soil P status, respectively.Keywords: Direct application, phosphate rock, soil available-P, upland acid soils.[How to Cite: Nurjaya and D Nursyamsi. 2013.

“…Calcification of acid soils increases the pH of the soil, which in turn releases phosphate ions which are precipitated with Al and Fe ions to make P available for plant absorption (Chimdi et al, 2012). (Kasno and Sutriadi, 2012). The effects of lime and manure require time to release P soil and for the mineralization process to take place.…”

Land use change is increasing, causing a lack of optimal land for agriculture. Marginal land improvement can be made with the application of organic amendments that can improve soil fertility to be optimal for crop cultivation. Land-use change is increasing, causing a lack of optimal land for agriculture. Marginal land improvement can be made with the application of organic amendments that can improve soil fertility to be optimal for crop cultivation. This study was carried out on acid soil of Karanganyar Regency. The treatments tested were P0 (control), P1 (2.5 t rock phosphate/ha + 5 t cow manure/ha), P2 (5 t rock phosphate/ha + 5 t cow manure /ha), P3 (2.5 t dolomite/ha + 5 t cow manure /ha), P4 (5 t dolomite/ha + 5 t cow manure/ha), P5 (5 t rock phosphate/ha + 5 t dolomite/ha + 5 t cow manure/ha) . The result showed that the application of P5 gave the highest yield of soybean of 1.41 t/ha. The application of manure significantly affected soil chemical properties of available P, available Ca, organic matter, and cation exchange capacity, but it did not significantly affect total N.
