Soil Quality Improvement

Intensive agriculture has been well known to cause decline in soil organic matter and nutrient content of the soils. Therefore, efforts should be taken to avoid this from happening. Addition of organic fertilizers like compost has been increasingly become more important in Indonesian agriculture in the last couple of decades. The objectives of this study were to produce high quality compost using Indore method and to investigate its effects on organic-corn production. The study was conducted in the Integrated Agriculture Zone (IAZ), University of Bengkulu for two years (2012 and 2013). The study  consisted of three steps: (i) soil fertility identification, (ii) compost production, and (iii) organic-corn field production. Soil fertility identification involved physical, chemical, biological analysis of soil samples collected from less fertile and moderately fertile soils. A randomized completely block design was employed in the field study which involved five rates of compost and two levels of soil fertility with three replications.  In 2012, high quality compost was black, had pH 8, fine, odorless, and sufficiently high in NPK contents. Organic-corn yielded 2.94 and 5.69 Mg ha-1 of dried kernels on less fertile and moderately fertile soils, respectively at 20 Mg ha-1 compost. Similarly, in 2013 high quality compost was black, had pH 8, moderate, odorless, and high in NPK contents. The corn yields were 3.75 and 1.93 Mg ha-1 on less fertile and moderately fertile soils, respectively at 22.50 Mg ha-1 compost.  [How to Cite: Riwandi, M Handajaningsih, Hasanudin, and A Munawar. 2015.

Introduction: Dental alginate impression material is the most common material used in dentistry. However, dental alginate waste (DAW) is one of the causes of the increasing number of dentistry and medicinal wastes. This research was aimed to discover the effect of dental alginate impression waste as additional fertiliser on the plant yields by determining the weight of cauliflower crop, and towards the quality of soil by determining the soil pH (Ultisol® Jatinangor). Methods: The experiment was using a randomised block design with 4 treatments and 7 times replications. The treatment consisted of A0 (0% DAW as control), A1 (0.01% DAW), A2 (0.1% DAW), and A3 (1% DAW). Results: The weight of cauliflower after addition of DAW in group A0 was 72.78; A1 was 139.82); A2 was 130.69; and A3 was 60.72). While the pH soil in group A0 was 5.92; A1 was 6.07; A2 was 6.02; and A3 was 6.26. The treatment in the A1 and A2 groups were found as the significant doses that able to increase the cauliflower weight for consecutively 1.92 times and 1.80 times compared to the control group, while on the soil quality improvement (soil pH), the addition of DAW was not significantly affected. Conclusion: It can be concluded that the addition of dental alginate waste at the dose of 0.01% and 0.1% increased the weight of cauliflower, but has no significant effect on the soil quality.

Organic And Inorganic Fertilizers

The study was carried out to determine the effect of organic and inorganic fertilizers on tomato yield and soil quality.  The study was performed in a randomized complete block design consisting of 7 treatments with 3 replications in the research farm, Shaikh Zayed University, Khost, Afghanistan. The fertilizers treatments were T1, organic fertilizer (5 t/ha); T2, organic fertilizer (10 t/ha); T3, urea (150 Kg/ha); T4, urea (200 Kg/ha); T5, mixed fertilizers (organic fertilizer 3 t/ha + urea (100 Kg/ha); T6, mixed fertilizers (organic fertilizer 6 t/ha + urea (70 Kg/ha) and T7 a control. Results indicate that applications of inorganic fertilizers with a combination of organic fertilizers increased tomato yield and improves the nutrient status of the soil. T5 showed the highest yield of tomato and followed by T4 treatment, which were 33.1 and 31.7 t/ha respectively. The lower yield were obtained in T7 and T1 treatments. The highest plant heights (205.0 and 199.0 cm) were obtained in T5 and T4 respectively, while the lowest plant heights were obtained in T1 treatment and followed by T7 treatment. Similarly, we found that a combination of both inorganic and organic fertilizers application also is the best strategy to improve soil nutrients, maintain soil fertility. Soil P2O5 and K2O, where the highest amounts were obtained in T5 and followed by T6, which were 26.5, 22.5 and 44.5 and 41.5 mg/L respectively. The control treatment had the lowest amount of P2O5 and K2O. Therefore, this study suggests that an appropriate amount of organic fertilizer with inorganic fertilizer not only increased tomato yield but also improve soil fertility.

Improved sorghum management practice can provide smallholder farmers with stability in their household nutritional needs and ensure food security. This study was therefore conducted to compare the effect of the single of two organic resources and their combined use with inorganic fertilizer (IN) on soil fertility and sorghum production. It was conducted in the Northern part of Burkina Faso. The treatments consisted of two levels of IN (the normal and the half dose of NPK + urea) and two types of organic resources (simple compost SC and Piliostigma reticulatum leaves compost CP). These treatments were combined to give 6 treatments: T1: control ; T2 : SC ; T3 : CP; T4 : SC + ½ dose of IN ; T5 : CP + ½ dose of IN ; T6 : normal dose of IN. The experiment was led using a randomized complete block design in three replications. The result revealed a greater  improvement of soil pH and nutrients induced by CP used alone. However, when combined with IN, it decreased significantly soil nutrients and  sorghum yield components and yield. Contrary, the SC in combination with IN gave the highest improvement in yield components and yield of sorghum. The use of IN alone increased sorghum yield components and yield but it contributed to decrease soil pH and nutrients content. A combined use of inorganic and organic fertilizers could be therefore recommended for maintaining soil fertility and for a sustainable production of sorghum.Keywords : Organic and inorganic resources, soil nutrients, sorghum yield.
