Sugarcane (Saccharum officinarum L.) is a variety of sources of carbohydrate as sugar production. Planting of sugar cane monoculture and continuously in dry land causes degradation of soil fertility. One effort to improve soil fertility is the addition of organic matter. through the use of blotong compost. The purpose of this paper is to provide information on blotong compost technology innovation in improving soil fertility and increasing sugarcane productivity.Blotong has potential as a source of organic material from the residual waste from sugarcane crop yields. The macro and micro nutrient content of compost in blotong compost plays an important role in supporting plant growth. Blotong compost application in the long term can increase the physical, biological and chemical fertility of degraded land. Blotong compost application with inorganic fertilizer can reduce the use of inorganic fertilizer. Blotong application can increase the nutrient content of N, P and micro elements in the soil and can increase the growth and productivity plant sugarcane.

Red Clay

Quaternary Red Clay (QRC) is the most common planting soil with low soil fertility and low crop yields in Southeast China, with low soil fertility and low crop yields. Many factors can impact the fertility and utilization efficiency of QRC. Here, we conducted a long-term fertilization experiment from 1984 to 2013. Five fertilization measures were carried out, including non-fertilization group; chemical Fertilizer group; 70% chemical and 30% organic fertilizer group; 50% chemical and 50% organic fertilizer group; 30% chemical and 70% organic fertilizer group. Soil organic matter (OM), total nitrogen (TN), total phosphorus (TP), total potassium (TK), soil microbial biomass carbon (SMBC) and nitrogen (SMBN), and soil enzymes activity were measured to evaluate the changes of soil. In addition, soil microorganisms were determined by high-throughput sequencing technology, and the dominant microbes were screened. The higher the proportion of organic fertilizer was, the higher the soil OM content was. The OM content of the non-fertilization group was the lowest. Similarly, SMBC and SMBN showed a consistent trend with OM content. Illumina sequence results showed that the application of organic fertilizer reduced the relative abundance of Chloroflexi, Acidobacteria and Nitrospirae, but increased Proteobacteria and Actinobacteria. The relative abundance of Acremonium and Mortierella were also greatly increased by different fertilization strategies. However, when high proportion of organic fertilizer was applied, the abundance of Acremonium and Mortierella decreased. Long-term balanced inorganic fertilization (NPK, 60%N:20%P:20%K) can effectively improve the quality and fertility of QRC. The effect of different fertilization strategies on fungi was greater than that on bacteria. The change of soil microorganism also proved the validity of inorganic fertilizer application.

Balanced nutrient supply is important for the sustainable crop production. We evaluated the effects of nutrient management practices on soil properties and crop yields in rice (Oryza sativa L.) - rice - wheat (Triticum aestivum L.) system in a long-term experiment established at National Wheat Research Program (NWRP), Bhairahawa, Nepal. The experiment was designed as a randomized complete block experiment with nine treatments and three replications. Treatments were applied as: T1- no nutrients added, T2- N added; T3- N and P added; T4- N and K added; T5- NPK added at recommended rate for all crops. Similarly, T6- only N added in rice and NPK in wheat at recommended rate; T7- half N; T8- half NP of recommended rate for both crops; and T9- farmyard manure (FYM) @10 Mg ha-1 for all crops in rotation. Results of the study revealed that rice and wheat yields were significantly greater under FYM than all other treatments. Treatments that did not receive P (T2, T3, T7, T8) and K (T2, T4) had considerably low wheat yield than treatments that received NPK (T5) and FYM (T9). The FYM lowered soil pH and improved soil organic matter (SOM), total nitrogen (TN), available phosphorus (P), and exchangeable potassium (K) contents than other treatments. Management practices that ensure nutrient supply can increase crop yield and improve soil fertility status.Int. J. Appl. Sci. Biotechnol. Vol 5(1): 42-50

Vegetable Cultivation

Vegetable cultivation is livelihoods for side Lake Batur communities, Kintamani, Bangli. Hilly natural conditions with a soil texture influenced by the eruption of Mount Batur, 900 m above sea level, and 900-3500 mm high rainfall, causing this region is very suitable for the cultivation of various vegetables, including shallot. One effort to meet the high demand for shallots is that efforts are made to improve cultivation techniques, including fertilizing to improve yields. In modern agriculture, the use of fertilizer is absolutely essential to trigger the level of crop production. The aims is to analyze the combination effect of using of inorganic fertilizer (ZA fertilizer) and organic fertilizer (compost fertilizer) on shallot vegetable cultivation systems on the content of pollutants, N nutrients and onion crop yields on the shores of Lake Batur, Kintamani District, Bangli Regency. The study using RBD with two factors where factor I: provision of organic fertilizer is leaf compost made aerobically (O), consisted of 3 levels, namely: O0 = 0*, O1 = 5* and O2 = 10*and factor II: the application of inorganic fertilizer namely ZA (S) fertilizer, consisted of 3 levels, namely: S0 = 0**, S1 = 50** and S2  = 100**, each repeated 3 times. The parameters observed were the growth and yield of shallots as well as the content of Pb, Zn, Cu and N nutrients in the soil. The nutrient content (N) in the soil, when using chemical fertilizer ZA and compost organic is not significantly different, as well as the results of onion plants, while the content of Pb, Zn and Cu on the use of chemical fertilizer ZA and organic compost, very real different. The highest soil Pb content in S2O1 treatment is 30.07***, the highest soil Zn content in the S2O1 treatment was 28.24***, and the highest soil Cu content in the S1O2 treatment is 17.22***. *= tons/ha **= kg/ha ***= mg/kg Keywords: compost; contents Pb; Zn; Cu of soil; shallot; ZA.

Summary Organic fertilization has been shown to benefit soil biota. A field experiment was established in 1991 at the AGES experimental research station Ritzlhof to investigate the effects of long-term fertilization on soil biota and crop yields. Experimental plots were cultivated using a crop rotation with maize, wheat, barley, and pea. Eight treatments consisted of compost application (urban organic waste, green waste, cattle manure, and sewage sludge compost). Composts were applied exclusively (organic) or amended with mineral nitrogen (N) fertilizers (80 kg N ha−1, organic-mineral) and compared to 0 (control) and mineral (40, 80, and 120 kg N ha−1) fertilization. Earthworm activity and biomass, litter decomposition, crop growth, and yield parameters were investigated under winter barley (Hordeum vulgare L.) in 2014 after uniform mineral fertilization and 1.5 years after the last compost application. Earthworm activity was significantly increased under long-term organic-mineral fertilization compared to the control, whereas earthworm biomass was unaffected by compost application. Litter decomposition rate was highest in the control. Only barley stem growth was affected by fertilization, whereas other barley parameters including yield were unaffected. The results showed that long-term fertilization affects soil biota even if compost is not applied every year.

Agroforestry Technology

Declining soil fertility is one of the major problems facing producers of field crops in most dryland areas of Sub-Saharan Africa. In response to the declining soil fertility, extensive participatory research has been undertaken by the World Agroforestry (ICRAF) and smallholder farmers in Dodoma region, Tanzania. The research has, amongst others, led to the development of Gliricidia agroforestry technology. The positive impact of Gliricidia intercropping on crop yields has been established. However, information on farmers’ willingness and ability to adopt the Gliricidia agroforestry technology on their farms is limited. This study predicts the adoption of Gliricidia agroforestry and conventional mineral fertilizer use technology. Focus Group Discussions (FGDs) were conducted with groups of farmers, purposively selected based on five sets of criteria: (i) at least 2 years of experience in either trying or using Gliricidia agroforestry technology, (ii) at least 1 year of experience in either trying or using the mineral fertilizer technology (iii) at least 10 years of living in the study villages, (iv) the age of 18 years and above, and (v) sex. The Adoption and Diffusion Outcome Prediction Tool (ADOPT) was used to predict the peak adoption levels and the respective time in years. A sensitivity analysis was conducted to assess the effect of change in adoption variables on predicted peak adoption levels and time to peak adoption. The results revealed variations in peak adoption levels with Gliricidia agroforestry technology exhibiting the highest peak of 67.6% in 12 years, and that the most influential variable to the peak adoption is the upfront cost of investing in Gliricidia agroforestry and fertilizer technologies. However, in Gliricidia agroforestry technology most production costs are incurred in the first year of project establishment but impact the long term biophysical and economic benefits. Moreover, farmers practicing agroforestry technology accrue environmental benefits, such as soil erosion control. Based on the results, it is plausible to argue that Gliricidia agroforestry technology has a high adoption potential and its adoption is influenced by investment costs. We recommend two actions to attract smallholder farmers investing in agroforestry technologies. First, enhancing farmers’ access to inputs at affordable prices. Second, raising farmers’ awareness of the long-term environmental benefits of Gliricidia agroforestry technology.

AbstractOrganic agriculture aims to build soil quality and provide long-term benefits to people and the environment; however, organic practices may reduce crop yields. This long-term study near Mead, NE was conducted to determine differences in soil fertility and crop yields among conventional and organic cropping systems between 1996 and 2007. The conventional system (CR) consisted of corn (Zea maysL.) or sorghum (Sorghum bicolor(L.) Moench)–soybean (Glycine max(L.) Merr.)–sorghum or corn–soybean, whereas the diversified conventional system (DIR) consisted of corn or sorghum–sorghum or corn–soybean–winter wheat (wheat,Triticum aestivumL.). The animal manure-based organic system (OAM) consisted of soybean–corn or sorghum–soybean–wheat, while the forage-based organic system (OFG) consisted of alfalfa (Medicago sativaL.)–alfalfa–corn or sorghum–wheat. Averaged across sampling years, soil organic matter content (OMC), P, pH, Ca, K, Mg and Zn in the top 15 cm of soil were greatest in the OAM system. However, by 2008 OMC was not different between the two organic systems despite almost two times greater carbon inputs in the OAM system. Corn, sorghum and soybean average annual yields were greatest in either of the two conventional systems (7.65, 6.36 and 2.60 Mg ha−1, respectively), whereas wheat yields were greatest in the OAM system (3.07 Mg ha−1). Relative to the mean of the conventional systems, corn yields were reduced by 13 and 33% in the OAM and OFG systems, respectively. Similarly, sorghum yields in the OAM and OFG systems were reduced by 16 and 27%, respectively. Soybean yields were 20% greater in the conventional systems compared with the OAM system. However, wheat yields were 10% greater in the OAM system compared with the conventional DIR system and 23% greater than yield in the OFG system. Alfalfa in the OFG system yielded an average of 7.41 Mg ha−1annually. Competitive yields of organic wheat and alfalfa along with the soil fertility benefits associated with animal manure and perennial forage suggest that aspects of the two organic systems be combined to maximize the productivity and sustainability of organic cropping systems.
