Organic Amendments Improve Wheat Root Growth and Yield through Regulating Soil Properties

An abandoned land after tin-mining activities are degraded lands with undulating and destructed land scape and low soil fertility status. The objective of this study was to determine the effects of organic amendments on the soil properties, growth, and grain yield of corn (Zea mays L.) on abandoned tin-mining areas in Bangka Island, Bangka Belitung Archipelago. The field experiment was conducted at the abandoned tin-mining areas in Cambai Village, Bangka Belitung Archipelago. Five treatments of organic amendments were applied and replicated three times and laid out in a Randomized Completely Block Design. All treatments were applied with the recommended rate fertilizer of 135 kg N ha-1, 72 kg P2O5 ha-1, and 120 kg K2O ha-1. The treatments were T1= 20 Mg chicken manure ha-1;T2= 20 Mg cattle manure ha-1; T3= 20 Mg rice straw compost ha-1; T4 : 10 Mg of chicken manure ha-1 + 10 Mg rice straw compost ha-1; and T5= 10 Mg cattlemanure ha-1 + 10 Mg rice straw compost ha-1. Application of organic amendments (chicken manure, cattle manure, and rice straw compost) on abandoned tin-mining land improved soil fertility due to the increasing of soil pH and nutrient availability, especially available-P and -K, and exchangeable bases. Application of chicken manure and cattle manure were significantly better than rice straw compost to improving soil fertility, nutrient uptake, growth and yield of maize. Application of cattle manure gave the highest yield of maize, namely 6.24 Mg ha-1.

A conversion period of at least two years is required for annual crops before produce may be certified as organically grown. There is a need for better understanding of the various management options for transitioning from conventional to organic production. The purpose of this study was to evaluate the effects of three organic amendments on growth and yield of bell pepper (Capsicum annuum L.), the benefit:cost ratio, soil fertility and enzymatic activities during conversion to organic production. The organic amendments were composted farmyard manure (FYMC), vermicompost (VC) and poultry manure (PM) along with biofertilizers [Azotobacter + Phosphorus solubilizing Bacteria (Pseudomonas striata)]. The bell pepper yield under organic management was markedly lower (33-53% and 18-40% less in first and second year of conversion, respectively) compared with conventional practice (FYMC 10 Mg ha-1 + NPK – 100:22:41.5 kg ha-1). Composted FYM 20 Mg ha-1 + biofertilizers (BF), and combined application of three organic amendments (FYMC 10 Mg ha-1 + PM and VC each 1.5 Mg ha-1 + BF) produced similar but significantly higher yield (27.9 and 26.1 Mg ha-1, respectively) of bell pepper compared with other organic amendment treatments. Composted FYM 20 Mg ha-1 + BF and combined application of three organic amendments greatly lowered soil bulk density (1.15-1.17 Mg m-3), and enhanced pH (7.1) and oxidizable organic carbon (1.2-1.3%) of soil compared with conventional practice and unamended control after a two-year transition period. However, the N, P and K levels were highest in the plots under conventional practice. Plots amended with FYMC 20 Mg ha-1 + BF had higher soil microbial activities of dehydrogenase, acid phosphatase and β-glucosidase compared with other treatments. However, the urease activity was greater in the plots under conventional practice. Among the treatments involving organic amendments alone, FYMC 20 Mg ha-1 + BF gave the highest gross margin (US $ 8237.5 ha-1) compared to other treatments. We conclude that FYMC 20 Mg ha-1 + BF was found more suitable for enhancing bell pepper growth and yield, through improved soil properties, during conversion to organic production.

Crop Root

Crop root growth and grain yield can be affected by chemical modifications in the soil profile due to surface lime application. A field trial was carried out on a loamy dystrophic Typic Hapludox at Ponta Grossa, State of Paraná, Brazil, to evaluate root growth and grain yield of wheat (Triticum aestivum L. cv. CD 104, moderately susceptible to Al), about 10 years after surface liming (0, 2, 4, and 6 Mg ha-1) and three years after surface re-liming (0 and 3 Mg ha-1), in a long-term no-till cultivation system. Soil acidity limited wheat root growth and yield severely, probably as a result of extended water deficits during the vegetative stage. Surface liming caused increases up to 66% in the root growth (0-60 cm) and up to 140% in the grain yield. Root density and grain yield were correlated positively with soil pH and exchangeable Ca2+, and negatively with exchangeable Al3+ and Al3+ saturation, in the surface and subsurface layers.
