Replacement of liming and NPK fertilization with turkey litter in degraded areas grown with Urochloa decumbens

Soil fertility and acidity correction in recovering areas require high doses of correctives and fertilizers. Therefore, the use of low-cost products may be an alternative in infertile areas. The objective of this study was to evaluate the effect of soil fertilization and correction methods on the yield of degraded areas cultivated with Urochloa decumbens and soil chemical attributes. The study was conducted in Orthic Quartzarenic Neosol in Mineiros, Goiás, Brazil, from October 2011 to September 2013. The experiment included soil samples treated with 2 Mg ha-1 of dolomitic limestone, a standard fertilizer (45, 54, and 75 kg ha-1 of N, P, and K, respectively), or 3 Mg ha-1 of turkey litter, and a control sample without correction/fertilization. Each treatment included four replicates in a completely randomized block design. The experimental plots consisted of areas of 4.0 m2 (2.0 ?? 2.0 m). The dry matter yield of forage grass and the following soil chemical attributes were evaluated: organic matter, hydrogen potential (pH in CaCl2), phosphorus (resin), potassium, calcium, magnesium, cation exchange capacity (CEC), and base saturation. The data were subjected to analysis of variance, and the means were compared using Tukey’s test at a level of significance of 0.05. Fertilization did not affect the pH, potassium, and CEC of the soil. Fertilization with turkey litter increased the levels of organic matter, phosphorus, calcium, magnesium, and base saturation compared with soils subjected to standard fertilization or liming. Furthermore, soils fertilized with turkey litter presented higher dry matter yield of Urochloa decumbens compared with unfertilized soils or soils subjected to acidity correction by liming but were not significantly different from soils treated with standard fertilizers. Therefore, fertilization with 3 Mg ha-1 of turkey litter is recommended for improving degraded pastures.

The aim of this study was to evaluate the behavior of chemical properties and crop yields during five years after liming, in a consolidated no-tillage system area and indicate a base saturation index to serve as a criterion for recommendation. The experiment was conducted in a randomized complete block design with four repetitions, being the treatments the five lime doses (0, 2.4, 4.8, 7.2 and 9.6 Mg ha-1) applied and maintained on the soil surface. Soil chemical properties were evaluated in eight soil sampling, in the layers 0 to 0.025; 0.025 to 0.05; 0.05 to 0.10; 0.10 to 0.15; 0.15 to 0.20 and 0.20 to 0.40 m, besides crop grain yield (wheat, soybean and corn) and black oat dry matter yield, totaling five years of evaluation. The surface liming in no-tillage system increased the exchangeable magnesium and calcium contents, base saturation and soil pH and reduced the exchangeable aluminum content. The cumulative grain yield (six crops) and black oat dry matter yield (three crops) was not influenced by liming. These results suggested, from this study conditions, that the value of 50% of base saturation should be adopted as a criterion for liming for crops implanted under consolidated no-tillage systems.

Ad Libitum Intake

Six mature Merino sheep received three treatments in a randomized block design experiment. The treatments were: chopped oaten hay diet at 90% of ad libitum intake without urea (L); the ciet offered at the same level as for L with urea infused into the rumen at 11.5 g kg-1 dry matter intake (LU); and the diet offered at 90% of the ad libitum intake achieved with urea infused at 11.5 g kg-1 dry matter intake (HU). Sheep given HU consumed 37% more (P < 0.01) organic matter (OM) than those fed L or LU, but the apparent digestibility of OM did not vary (59.2-61.8%) between treatments. The addit onal food consumption was associated with c. 20% increase (P < 0.05) in the weight of OM in the reticulorumen and significantly higher (by 10-35%; P < 0.05) fractional outflow rates of most dietary and microbial constituents of digesta. The fractional digestion rate of potentially digestible plant cell walls was not affected by urea, but the flow of microbial non-ammonia nitrogen from the abomasum was enhanced (L, 7.0; LU, 8.2; HU, 12.5 g day-1; P < 0.05). The results of this study suggest that the stimulatory effect of urea upon food intake was associated with the provision of additional microbial protein for digestion in the intestines, rather than changes in the rate or extent of organic matter fermentation in the reticulorumen.

A study was conducted to determine the best agronomic practices for the cultivation of jerangau merah as a new medicinal crop. Jerangau merah is scientifically known as Boesenbergia stenophylla is a ginger plants that is highly endemic to the Borneo Highland. This understorey herb grows in cluster and under the heavy shades of forest canopies and perceived only the sunflecks that pass through the forest canopies. Jerangau Merah has been consumed by the locals for its medicinal values since decades ago. Generally, B. stenophylla is well known for its function as antidote for alcohol. Moreover, the B. stenophylla is also beneficial for rheumatic pains, remedies for stomach ache and toothache and as antiseptic wash as well. This herb is not propagate by the locals due to its sensitivity to sunlight and lack of agronomic information for B. stenophylla. Harvesting it from their natural habitat, however, seen the decline it its population size hence cultivation is essential. This paper aimed to determine the total nutrients, dry matter yield and phytochrome content of Bosenbergia stenophylla R.M. Smith under different light regimes. A study for determining suitable planting media for B. stenophylla was conducted at Universiti Putra Malaysia (UPM). The treatments are: i) (M1) with the ratio of 3:2:1 top soil: sand: organic matter, media ii) (M2) consists of soil mixture 3:2:1 placed in water-logged polyethylene bags and media iii) (M3) contained only leaf litters. The results showed that the herbs showed significantly higher number of shoots and leaves in the common soil mixture. But, better root development in media containing leaf litters. The study proceeded with field experiment at Ba’Kelalan to determine the effect of different shade levels and fertilizing regimes on growth. B. stenophylla was cultivated under two different levels of shade cloths: 70% and 90% level of shade and different fertilizing regimes (T1 as control, no fertilizer applied to the plants; T2, chicken dung; T3, NPKMg and T4, mixed of chicken dung and NPKMg). The study for determining the effects of different shade level and fertilizing regimes on seedling’s growth which conducted at Ba’Kelalan in factorial randomized completely blocked design (RCBD). The data collected for 9 weeks of planting which include nutrient content in soil, leaf, PAR and phytochrome content and growth parameters. Regarding the nutrient uptake, the results showed no interactions between fertilizing regimes and shade levels. There were no significant different in nutrient elements except for magnesium and potassium. Magnesium is essential for the formation of chlorophyll which ensure efficiency of photosynthesis when under higher light intensity. Among all the fertilizer treatment, it was showed that chicken dung amendment has higher nutrient uptake. Thus, it is recommended chicken dung should be added into the NPKMg for better nutrient uptake. Further study on suitable fertilizer rates apply to B. stenophylla should be taken into consideration. Moreover, plants cultivated under 70% have been higher and have higher dry matter yield than those plants cultivated under 90%. The result also revealed that there was significant different in chlorophyll content of B. stenophylla cultivated under 70% which treated either with chicken dung and NPKMG respectively. However, plants under 90% have higher chlorophyll content than those under 70%. Based on the results, plants under 70% shade was taller than those under 90% and there were significant difference in height among treatments under 70%. It was observed plant treated with NPKMg was taller. This study showed that shade and fertilizers significantly affected the dry matter yield of B. stenophylla. Moreover, adding NPKMg to the treatments yields more dry matter content of jerangau merah. As for phytochrome content, there was no significant effect of fertilizer on phytochrome content. However, there was significant difference among the shade levels. 90% shade showed higher phytochrome content than those under 70%. In overall, both shade and fertilizer is important in cultivation of Jerangau Merah. 70% shade was observed to have significant effects on growth of jerangau merah and also more economical compared to 90%. Moreover, combination of organic matter and NPKMg also promote the growth of jerangau merah enhance the nutrient uptake efficiency of jerangau merah. However, further investigation of suitable fertilizer and application rate are required to determine suitable fertilizer for jerangau merah and application rate for optimum growth of jerangau merah.

An experiment was conducted to evaluate the effect of growth, biomas yieds and nutritive value of Lablab purpureus, Centrosema pubescens and Mucuna pruriens under rain fed condition in Yola, Adamawa State, Nigeria. The field experiment was laid in a randomized complete block design with the plot divided into three main plots and replicated three times measuring 5x5m with inter and intra row spacings of 0.5m. The five harvesting stages are 6, 8, 10, 12 and 14 weeks, respectively. The growth in height increases with stage of growth and declined with reduction in rainfall. Higher growth were recorded in T3 (3.8 -354.8cm) followed by T2 (2.96-260.20cm) and then T1 (1.50-213.00cm) and the results were presented graphically. The result of the chemical composition of all the legumes showed that the crude protein decreases with stage of growth from weeks 6 -14 (14.40, 12.26, 10.65-10.08, 6.79, 6.49) and ADF and NDF (25.20, 32.15, 27.35-42.13, 40.33, 36.50 and 32.20, 54.45, 47.00- 51.24, 63.53, 66.33), respectively. The biomass yields were significantly different (P<0.05) for all the legumes at different harvesting stages T1 (2744.53-3186.93), T2 (2696.47- 3006.70) and T3 (2843.73-3147.63). It is therefore concluded that legumes could best be harvested between weeks 10 and 12 when the yield and quality are at levels to sustain the animals both for maintenance and production.

Com a expansão da agricultura as florestas têm sido fragmentadas, modificando a dinâmica dos seus processos refletindo na fertilidade do solo. Esse estudo teve como objetivo avaliar o efeito de borda na fertilidade do solo em um fragmento florestal na região Sudoeste da Bahia. Para isso a área foi dividida em faixas verticais iniciando 50 metros após a borda, adentrando até 300 metros no fragmento. Em cada uma das faixas foram tomadas 3 amostras compostas nas profundidades de 0-5, 5-10, 10-20 cm. Analisando os atributos químico e calculando a soma de bases, CTC a pH7 e a saturação por bases (V%). Também foram quantificados os teores de carbono orgânico (COT) nas áreas de estudo. Foram observadas diferenças na fertilidade do solo da borda para o interior do fragmento. Verificou-se que os atributos Ca2+, H++Al3+, S, T, COT foram os mais sensíveis em relação ao efeito de borda. A área semi-interna (SI) distando 150-200 metros, de maneira geral foi a que apresentou os maiores valores de fertilidade do solo, possivelmente devido aos maiores teores de matéria orgânica acumulada. Soil fertility as edge effect indicator in a forest fragment, Vitória da Conquista, BahiaAbstract: With the expansion of agriculture forests have been fragmented, changing the dynamics of their processes reflecting soil fertility. This study aimed to evaluate the edge effect on soil fertility in a forest fragment in the Southwest Bahia region. For this area was divided into vertical strips starting 50 meters after the border, entering up to 300 meters in the fragment. In each of the tracks were taken 3 composite samples at depths of 0-5, 5-10, 10-20 cm. Analyzing the chemical attributes and calculating the sum of bases, CTC at pH 7 and base saturation (V%). Also the organic carbon levels were quantified (COT) in the study areas. Differences were observed at the edge of soil fertility into the fragment. It was found that attributes, Ca2+, H++Al3+, S, T, COT were the most sensitive in relation to the edge effect. The semi-internal area (SI) 150-200 meters distant in general was the one with the highest soil fertility values, possibly due to higher levels of accumulated organic matter.
