“…Moreover, the LM plot had higher TN and TC content at the end of the study than the other two plots ( Table 1). The expected improvement of soil physical properties by organic matter application from fermented cattle manure [20,21] was evidenced by comparison with pre-established DL Napiergrass plots. Organic matter components usually encourage the formation of stable soil crumb structure, thus improving soil internal drainage, infiltration, aeration and microbial activity and root development.…”

“…Since manure has a high concentration of organic matter, its application as a fertilizer helps decelerate depletion of organic matter in arable land, especially when there is a high frequency of heavy erosion [12][13][14]. It also increases the soil levels of the macroelements of nitrogen (N), phosphorus (P), and potassium (K) [15][16][17][18][19], improves soil physical properties [20,21], enhances DM yield [22][23][24][25], and improves the crude protein concentration of herbages [26].…”

Abstract:The effects of two levels of manure application (184 and 275 kg N ha −1 year −1 ) on herbage yield, quality, and wintering ability during the cropping of a dwarf genotype of late-heading (DL) Napiergrass (Pennisetum purpureum Schumach) oversown with Italian ryegrass (IR; Lolium multiflorum Lam.) were examined and compared with chemical fertilizer application (234 kg N ha −1 year −1 ) for 4 years to determine a sustainable and environmentally harmonized herbage production in a hilly area (340 m above sea level). No significant (p > 0.05) differences in growth attributes of plant height, tiller density, percentage of leaf blade, or dry matter yield appeared in either DL Napiergrass or IR among moderate levels (184-275 kg N ha −1 year −1 ) of manure and chemical fertilizer treatments. IR exhibited no significant detrimental effect on spring regrowth of DL Napiergrass, which showed a high wintering ability in all treatments. In vitro dry matter digestibility of DL Napiergrass tended to increase with increasing manure application, especially at the first defoliation in the first three years. Manure application improved soil chemical properties and total nitrogen and carbon content. The results suggested that the lower rate of manure application of 184 kg nitrogen ha −1 year −1 would be suitable, which would be a good substitute for chemical fertilizer application with an equilibrium nitrogen budget for sustainable DL Napiergrass and IR cropping in the hilly region of southern Kyushu.

“…Benbi et al (1998) and Bhattacharyya et al (2007) studied change in soil physical properties due to organic matter addition under dry tropical conditions in India. In both cases, farmyard manure addition to soils with loamy sand and silty clay loam texture and low initial organic carbon of 2 and 7 g kg −1 TOC, respectively, enhanced aggregation, resulting in higher saturated hydraulic conductivity.…”

Drought is a predominant cause of low yields worldwide. There is an urgent need for more water efficient cropping systems facing large water consumption of irrigated agriculture and high unproductive losses via runoff and evaporation. Identification of yield-limiting constraints in the plant-soil-atmosphere continuum are the key to improved management of plant water stress. Crop ecology provides a systematic approach for this purpose integrating soil hydrology and plant physiology into the context of crop production. We review main climate, soil and plant properties and processes that determine yield in different water-limited environments. From this analysis, management measures for cropping systems under specific drought conditions are derived. Major findings from literature analysis are as follows. (1) Unproductive water losses such as evaporation and runoff increase from continental in-season rainfall climates to storage-dependent winter rainfall climates. Highest losses occur under tropical residual moisture regimes with short intense rainy season. (2) Sites with a climatic dry season require adaptation via phenology and water saving to ensure stable yields. Intermittent droughts can be buffered via the root system, which is still largely underutilised for better stress resistance. (3) At short-term better management options such as mulching and date of seeding allow to adjust cropping systems to site constraints. Adapted cultivars can improve the synchronisation between crop water demand and soil supply. At long term, soil hydraulic and plant physiological constraints can be overcome by changing tillage systems and breeding new varieties with higher stress resistance. (4) Interactions between plant and soil, particularly in the rhizosphere, are a way towards better crop water supply. Targeted management of such plant-soil interactions is still at infancy.We conclude that understanding site-specific stress hydrology is imperative to select the most efficient measures to mitigate stress. Major progress in future can be expected from crop ecology focussing on the management of complex plant (root)-soil interactions.

“…The effect of organic matter is mainly due to the improvement of the physical (Schjønning et al, 1994;Benbi et al, 1998) and electrochemical (MacCarthy et al, 1990) properties of soils, often related to soil remediation and soil reclamation. In relation to nutrient supply, application of organic residues may reduce the amount of mineral fertilization required, and so consequently information is needed to quantify nutrient availability from organic sources (Brady and Weil, 1996), since environmental and economic pressure on agriculture has prompted farmers to make more efficient use of nutrients.…”
