Penggunaan lahan basah menemui berbagai kendala kesuburan dan kesehatan tanah serta sulit dalam pengelolaan air, karena itu perlu dikembangkan model intensifikasi dalam pemanfaatan lahan basah sub-optimal. Dari berbagai model intensifikasi tersebut, salah satunya dengan teknik konservasi tanah. Teknik konservasi tanah yang dapat dilakukan dengan menggunakan bahan-bahan sisa panen tanaman pertanian, perkebunan dan material sisa agroindustri yang sangat melimpah jumlahnya. Dalam tulisan ini, dipaparkan metode pembuatan dan hasil implemensi kompos, bokashi dan biochar sebagai pembenah tanah mineral serta hasil implementasi abu batubara sebagai zeolit pada gambut. Tujuan penulisan ini untuk memberikan informasi tentang potensi dan manfaat jerami padi, tandan kosong kelapa sawit (TKKS), kayu apu dan abu boiler hasil pembakaran batubara maupun serat dan cangkang kelapa sawit sebagai pembenah tanah. Potensi pembenah tanah berbahan dasar jerami padi, tandan kosong kelapa sawit (TKKS), kayu apu dan abu boiler hasil pembakaran serat dan  cangkang, terbukti mampu mengoptimalkan ketersediaan hara dalam tanah, mengurangi penggunaan pupuk sintetis serta mendorong ekosistem kesehatan dan kesuburan tanah. Pembenah tanah berupa bahan organik dapat menjadi buffer capacity bagi tanah mineral, memunculkan sifat slow release fertilizer pada kegiatan pemupukan serta mengurangi efek dan kerusakan lahan, sedangkan implikasi abu batubara sebahai zeolit mampu menyediakan mineral dan memperbaiki karakter fisik gambut.Kata kunci :  agroindustri, ameliorasi, sub-optimal, TKKS, biochar

AbstractUrea-based multi-coated slow release fertilizer was produced using water hyacinth, humic substances, and chitosan, with water rich in natural organic matter as a solvent. Elemental analysis showed that the nitrogen content of the fertilizer (FERT) was around 20%. Swelling tests demonstrated the effectiveness of the water hyacinth crosslinker, which reduced the water permeability of the material. Leaching tests showed that FERT released a very low concentration of ammonium (0.82 mg L−1), compared to the amount released from urea (43.1 mg L−1). No nitrate leaching was observed for FERT, while urea leached 13.1 mg L−1 of nitrate. In water and soil, FERT showed maximum releases after 30 and 40 days, respectively, while urea reached maxima in just 2 and 5 days, respectively. The results demonstrated the promising ability of FERT to reduce nitrogen losses, as well as to minimize environmental impacts in the soil–plant-atmosphere system and to improve the efficiency of nitrogen fertilization.

Composted Sewage Sludge

Collaborative research between Southern Water and Wye College, University of London, has led to the development of a static aerated pile composting process for the treatment of dewatered activated sludge cake/straw mixtures. The process reduces bulk volume of the sludge producing an environmentally acceptable, stabilised, odour and pathogen-free product. Characteristics of the compost make it a suitable general purpose medium for container grown plants, providing the salt concentration is reduced by washing the compost prior to planting. Compared with peat the compost has a higher bulk density, a lower waterholding capacity, a lower cation exchange capacity, a high content of soluble salts, and a higher content of plant nutrients. A compost mixture was successfully developed in the growing trials containing equal quantities of compost, Sphagnum peat, and horticultural vermiculite. The compost has been used successfully to grow a wide range of plants. Plants grown in mixtures based on the compost were in general similar to those grown in peat-based growing media. The compost is a valuable soil conditioner and slow release fertilizer.
