Experiments were conducted to study the effect of inorganic, organic and combined inorganic + organic fertilizer and natural shade under Gliricidia on the growth and dry matter (DM) yield of the medicinal plant Solanum virginianum Schrad. The yield of total dry matter and of different plant parts were also studied in plants harvested at 70, 90 and 110 days after establishment. Application of co...

The surface mining activities in the past and in recent times has resulted into existence of number of overburden dumps through excavation and depositing removed soil and rock debris. These dumps require environmental stabilization/restoration, through proper revegetation. To achieve this aim, a study was conducted to find the efficacy of Mung bean (Vigna radiata L.), an economically important ...

With the increases of cropland area and fertilizer nitrogen (N) application rate, general N balance characteristics in regional agroecosystems have been widely documented. However, few studies have quantitatively analyzed the drivers of spatial changes in the N budget. We constructed a mass balance model of the N budget at the soil surface using a database of county-level agricultural statistic...

Analysis of macrophyte water hyacinth (Eichhornia crassipes) as an organic fertilizer of Colossoma macropomum (tambaqui) larvae in ponds is provided. Water hyacinth produce an organic fertilizer at the ratio of 100 g x m(-2) in tambaqui ponds. Two groups of 5,000 larvae were transferred to two fishponds with and without water hyacinth fertilizer and reared until day 43. The fertilized pond evid...

1 Plant species diversity drops when fertilizer is added or productivity increases. To explain this, the total competition hypothesis predicts that competition above ground and below ground both become more important, leading to more competitive exclusion, whereas the light competition hypothesis predicts that a shift from below-ground to above-ground competition has a similar effect. The densi...

Tomato bacterial wilt caused by Ralstonia solanacearum is one of the most destructive soil-borne diseases. Many strategies have been taken to improve soil suppressiveness against this destructive disease, but limited success has been achieved. In this study, a novel bioorganic fertilizer revealed a higher suppressive ability against bacterial wilt compared with several soil management methods i...

Nonpoint-source pollution from agricultural activities is currently the leading cause of degradation of waterways in the United States. Applying best management practices to flood-irrigated mountain meadows may improve agricultural runoff and return flow water quality. Prior research has focused on fertilizer use for increased hay yields, while few studies have investigated the environmental im...

Fertilizer-intensive soya bean agriculture has recently expanded in southeastern Amazonia, and whereas intensive fertilizer use in the temperate zone has led to widespread eutrophication of freshwater ecosystems, the effects in tropical systems are less well understood. We examined the fate of fertilizer phosphorus (P) by comparing P forms and budgets across a chronosequence of soya bean fields...

Water vapor transport plays a significant role in maintaining the water cycle over Tibetan Plateau (TP). This study investigates characteristics of across TP southern boundaries and its impacts on precipitation during Indian summer monsoon (ISM) season from 2000 to 2019. The boundary is subdivided into four sub-boundaries east west: 7 (100°–95° E), 8 (95°–89° 9 (89°–80° 10 (80°–70° E) (B7, B8, ...
