Abstract

Pepper (Piper nigrum L.) has a high selling value. The price of pepper in the domestic or international market that is always high can be a great opportunity to increase farmers’ income. Tirtomoyo District is dominated by hilly areas with common soil types of Litosol and Latosol. As one of the efforts to develop the regional economic rate, especially in hilly areas, pepper cultivation can be a solution offered by the agricultural sector. The study was conducted using an explorative descriptive survey method consisting of field observation and laboratory analysis. The analytical unit used was Land Map Unit (LMU) obtained from soil map. The sampling sites were selected using purposive sampling method according to the research objectives and representing the study area. The results show that the actual land suitability for pepper in Tirtomoyo District is marginally suitable (S3) for all LMU. The main limiting factors are water availability and nutrient availability, thus the Tirtomoyo district still have potency for pepper cultivation by applying some improvement measures such as fertilization, irrigation, organic material addition, and cover crop planting.

Abstract

Uncontrolled land conversion causes reduced land area for plant cultivation. The alternative used for rice cultivation is the marginal land such as sandy soil, however, several constraints led to very low productivity, so it needs proper management such as the addition of organic matter. The purpose of this study was to determine the changes in the chemical properties of sandy soil treated with Azolla microphylla and quail manure. The pot research was carried out in the Greenhouse of the Faculty of Agriculture, Universitas Sebelas Maret, with a factorial Completely Randomized Design (CRD) method, with 2 factors. Factor I was Azolla microphylla (A) (A0= 0, A1= 50, A2= 100, A3= 150 tons ha-1). Factor II was quail manure (Q) (Q0= 0, Q1= 20, Q2= 40 tons ha-1). Azolla microphylla and quail manure were incubated for 14 days under anaerobic conditions. The results showed that the application Azolla microphylla and quail manure increased chemical properties on sandy soil significantly. The addition of Azolla microphylla (100 tons ha-1) and quail manure (40 tons ha-1) increased the chemical properties of sandy soil such as cation exchange capacity (CEC), available-P, ammonium, available-K, available-Ca, electrical conductivity (EC) and redox potential (Eh).

Abstract

Uncontrolled land conversion reduces the available land for plant cultivation. The alternative used for rice cultivation is marginal land, such as sandy soil. However, several constraints led to very low productivity, so it needs proper management, such as adding organic matter. This study aimed to determine changes in the chemical properties of sandy soil treated with Azolla microphylla and quail manure. The pot research was carried out in the Greenhouse of the Faculty of Agriculture, Universitas Sebelas Maret, using a factorial Completely Randomized Design (CRD) with two factors. The first factor consisted of four levels of Azolla microphylla (AM),i.e., (0, 50,100, and 150 Mg ha-1). The second factor was three-level quail manure (QM ), i.e., (0, 20, 40 Mg ha-1). Fresh Azolla microphylla and quail manure were incubated for 14 days under anaerobic conditions. The results showed that applying Azolla microphylla, with or without quail manure, significantly improved the chemical properties of sandy soil. The addition of Azolla microphylla (100 Mg ha-1) with quail manure (40 Mg ha-1) increased organic C, Cation exchange capacity (CEC), available-P, Ammonium, Nitrate, exchangeable-K, Ca, electrical conductivity (EC), and redox potential (Eh).
