“…Ternyata kandungan N-totalnya pada kedua lahan itu masing-masing 0.36% dan 0.31%, yang tergolong sedang (BPT, 2009). Menurut He et al (2018) dan Alfaro et al (2018), penambahan pupuk N saja relatif tidak menyebabkan kenaikkan nilai respirasi tanah, jadi harus diikutkan penambahan bahan organik supaya nilai respirasi tanah meningkat. Untuk nilai respirasi tanah yang cukup tinggi dari penelitian ini untuk lahan kentang terdapat di Desa Condong Campur, Kabupaten Banjarnegara 10.97 mg C-CO2 kg -1 tanah hari -1 dan untuk lahan ubi jalar terdapat di di Desa Larangan Lor, Kabupaten Wonosobo yang nilainya 0.80 mg C-CO2 kg -1 tanah hari -1 .…”

Prominent problems in suboptimal land are often only related to the chemical and physical properties of the soil such as low soil pH, available nutrients and the ability of the soil to supply available water. Assessment of soil biological characteristics is needed to look at soil problems on dry land more comprehensively. The purpose of this study was to conduct a preliminary study of the variability of soil biological characteristics in suboptimal dry land. This study was carried out with a field survey accompanied by soil sampling using a composite method in 24 land locations which are the centers of development of the Department of Agriculture commodity development in five districts in Central Java Province that were randomly selected. In addition to soil organic matter, soil biological characteristic studied was the total number of soil microorganisms. The results of the study on both potato and sweet potato commodity lands showed there were intervals of the number of soil microorganisms, namely 1.83 x 10 5-1.63 x 10 6 CFU g-1 of soil and 3.90 x 10 5-1.10 x 10 6 CFU g-1 of soil. While the interval of soil respiration value is 4.80-10.97 mg C-CO2 kg-1 of soil day-1 for potato commodity land and 5.31-10.80 mg C-CO2 kg-1 of soil day-1 for sweet potato land. There was no strong correlation between the number of soil microorganisms and soil respiration, which was indicated by a correlation value of 0.29. The biological characteristics of the soil varied greatly, and they did not affect the type of commodity or location.

“…Availability of N, P, and K after treatment (recovery nutrient) was higher in soils with N. biserrata and A. gangetica than without cover crops (Table 2). Dube and Stolpe (2016) and Alfaro et al (2018) reported that soil nutrient availability was higher in soil covered by cover crops than without cover crops. According to Alfaro et al (2018), availability of soil nutrients is related to cover crops.…”

“…This is due to the interaction between the quantity and quality of organic residues that enter the soil and the subsequent use of soil macro and microorganisms will affect the accumulation rate of organic and soil nutrients (Dube and Stolpe, 2016;Wang et al, 2017). Litter accumulation is higher in the soil with cover crop than without cover crops (Alfaro et al, 2018).…”

Nutrient recycling and mineral balance are important factors affecting nutrient budgets in oil palm (Elaeis guineensis Jacq.) plantations. The nutrient budget includes processes such as plant uptake, removal by harvesting, accumulation or storage in the standing plant, and recycling through decomposition of cover crop Asystasia gangetica (L.) T. Anderson can be utilized as cover crops in mature oil palm plantations with appropriate management. This study aimed to examine the growth of A. gangetica in 17 yr old oil palm plantations with different populations, understanding the contribution of A. gangetica to improve available nutrient in the plantation on the nutrient balance, and to study its role as cover crop in the mature oil palm plantation. The experiment was conducted in an experiment field of 17 yr old of mature oil palm at Bogor, Indonesia. Results showed that A. gangetica can be used as cover crops in mature oil palm plantations because it meets several conditions such as rapidly covering the land (11 wk after planting), and able to increase the available N, P, K as much as 18.49%, 9.20%, 38.36%, respectively, based on the nutrient balance with the optimum population is 1 000 000 plants ha-1 .

“…Practices such as agroforestry and conservation agriculture systems have the potential to conserve soil and water resources, improve ecosystems services and restore soil organic C (Alfaro et al, 2018) through increased C inputs from higher biomass productivity (Corbeels et al, 2019;Kumar et al, 2020). However, agroforestry systems in the Mediterranean climate region of central Chile are highly dependent on precipitation, which is concentrated in winter.…”

The agroforestry activity of central Chile is developed under Mediterranean climate, characterized by long periods of water deficit conditions, particularly on hillsides with degraded and compacted soils. The objective of this study was to assess the effect of two soil and water conservation techniques on soil water content (SWC) and in plant growth and survival of three tree species. The conservation techniques evaluated were subsoiling with contour ridges (SB) and infiltration trench (IT), and a control treatment without soil management (CO). Growth and survival of Cytisus proliferus L. f. var. proliferus, Quercus suber L. and Quillaja saponaria Molina were examined. The experimental area was sown with a mixture of annual legumes. Conservation systems allowed higher SWC especially in years of higher rainfall (2008 and 2009) at 20-40 and 40-60 cm depth. SWC was higher in SB followed by IT and CO, whereas at 60-80 and 80-100 cm depth differences were significant only in the driest years. After 4 yr, plant survival of C. proliferus and Q. suber was similar in the three establishment systems (97% and 87%, respectively), but survival of Q. saponaria was lower in CO. Plant height in C. proliferus was higher in IT > SB > CO, while Q. suber was higher in SB > IT > CO; Q. saponaria had similar growth in SB and IT conservation systems but it was significantly higher (P < 0.05) than in CO. It is concluded that subsoiling with ridges has a great potential for degraded and compact soils of the Mediterranean region, allowing higher SWC in the profile and better tree establishment and growth.
