Damatta Bio Farmer (Cezar Villela), Brazil - Case Study
EFFECTS OF VARYING COVER CROPS ON SOIL RESPIRATION IN A BRAZILIAN OXISOL A Cover Crop/ Soil Respiration Study in Brazil: Validating gains in soil biology with Solvita CO2 – results after 1 growing season. Brazilian Oxisols are high in clay with low natural fertility. This poses a challenge for growers. To test the potential for soil improvement various grasses and legumes were grown for an ...

Use of nuclear techniques in the study of the behaviour of rare earth elements on the use of phosphogypsum in Cerrado agriculture
Phosphogypsum (PG) is a by-product of phosphoric acid industry. In Brazil, this material has been used as a conditioner for soils with high levels of aluminium. Taking into account the presence of radionuclides and Rare Earth Elements (REEs) in this material, a research project has been conducted in order to investigate the impact of using PG in crops cultivated in Cerrado soils. For this purpose ...

Soil phosphorus
As I "dig" deeper into the soil microbial world I am amazed how much we understand but few utilize what we do know. The word is getting out that if we let the soil microbes thrive and multiply by feeding our soil degradable plant and organic material the microbes will give our plants and crops back the nutrients they need. We are now finding that by adding fertilizers directly in the inorganic ...

Evaluating the effect of climate variation on the cost efficiency of a crop permit policy in Southern Sweden
Current international agreements call for a significant reduction of nitrogen loads to the Baltic Sea. New measures to reduce nitrogen loads from the agricultural sector and an increased focus on cost efficiency will be needed to meet reduction targets. For policy design and evaluation it is important to understand the impact of weather on the efficiency of abatement measures. One new proposed ...

Methane flux in cropland and adjacent riparian buffers with different vegetation covers
Received for publication September 12, 2008. While water quality functions of conservation buffers established adjacent to cropped fields have been widely documented, the relative contribution of these re-established perennial plant systems to greenhouse gases has not been completely documented. In the case of methane (CH4), these systems have the potential to serve as sinks of CH4 or may provide ...

Development of a decision support system for small reservoir irrigation systems in rainfed and drought prone areas
An integrated computer program called Cropping System and Water Management Model (CSWM) with a three-step feature (expert system—simulation—optimization) was developed to address a range of decision support for rainfed farming, i.e. crop selection, scheduling and optimisation. The system was used for agricultural planning with emphasis on sustainable agriculture in the rainfed areas through the ...

Ag in Motion 2020: Virtual Content
Field days and trade shows looked a little different than usual in 2020. In July, Kendall Gee of Crop Intelligence, and Curtis Russell with Taurus Ag Marketing https://www.taurus.ag/team/ met in a canola field southeast of Regina to discuss how soil moisture data can help inform farm decision making throughout the growing season. The video includes a walk-through of live data from Crop ...

Market waste composting in Lima, Peru
The Empresa de Servicios Municipales de Limpieza de Lima (ESMLL and the Pan American Center for Sanitary Engineering and Environmental Sciences (CEPIS) carried out in 1993 a joint research project oriented toward the recovery and use of market waste for compost production to benefit from the wastes generated in Lima.. This pilot project represents an effort aimed at solving the major waste ...

Soil quality and corn yield under crop–livestock integration in Illinois
Compared with traditional cropping systems, integrated crop–livestock systems have shown greater efficiency in improving soil quality and crop yield. The objective of this study was to determine how an integrated crop–livestock system affected soil properties and corn (Zea mays L.) yield when compared with continuous corn (CC). The study was conducted from 2004–2008 on a large-scale research farm ...

Effect of exo-polysaccharides producing bacterial inoculation on growth of roots of wheat (Triticum aestivum L.) plants grown in a salt-affected soil
Abstract: Effect of soil salinity on physico-chemical and biological properties renders the salt-affected soils unsuitable for soil microbial processes and growth of the crop plants. Soil aggregation around roots of the plants is a function of the bacterial exo-polysaccharides (EPS), however, such a role of the EPS-producing bacteria in the saline environments has rarely been investigated. Pot ...

PRZM-3, A Model for Predicting Pesticide and Nitrogen Fate in the Crop Root and Unsaturated Soil Zones: Users Manual for Release 3.12.2
This publication contains documentation for the PRZM-3 model. PRZM-3 is the most recent version of a modeling system that links two subordinate models – PRZM and VADOFT – in order to predict pesticide transport and transformation down through the crop root and unsaturated soil zones. Enhancements to Release 3.0 reported herein include algorithms that also enable modeling of the nitrogen cycle ...

Modeling Nitrogen and water management effects in a Wheat-Maize double-cropping system
Excessive N and water use in agriculture causes environmental degradation and can potentially jeopardize the sustainability of the system. A field study was conducted from 2000 to 2002 to study the effects of four N treatments (0, 100, 200, and 300 kg N ha–1 per crop) on a wheat (Triticum aestivum L.) and maize (Zea mays L.) double cropping system under 70 ± 15% field capacity in the North China ...

Corn stover to sustain soil organic carbon further constrains biomass supply
Sustainable aboveground crop biomass harvest estimates for cellulosic ethanol production, to date, have been limited by the need for residue to control erosion. Recently, estimates of the amount of corn (Zea mays L.) stover needed to maintain soil carbon, which is responsible for favorable soil properties, were reported (5.25–12.50 Mg ha–1). These estimates indicate stover needed to maintain soil ...

Stockwell on Soil: Logic On Side of Cover Crops & No-Till
While reading this article I noticed #6 in the list includes cover crops and no till. We often talk about the very same benefits discussed in number six, but the important lesson here is the frame. First, the opening or introductory message is NOT about cover crops or soil health. As much as we all love to delve into those topics, the majority of producers do not (I know, hard to believe, but ...

Soil properties and crop yields in response to mixed paper mill sludges, dairy cattle manure, and inorganic fertilizer application
The contribution of organic wastes to crop yields and soil fertility may be influenced by their composition and the soil type. This 6-yr study (2001–2006) evaluated the effects of repeated additions of mineral fertilizers (MF), mixed paper mill sludges (PMS) (18, 36, and 54 Mg ha–1), dairy cattle manure (DCM) (36 Mg ha–1) alone or with reduced mineral fertilizer (60% NPK) (RMF) and a control, on ...

Soil water surplus and ENSO events during the last humid period in Argentine Pampean flatlands
Daily soil water balances are estimated for the period 1951-2006 in the Pampean flatlands. Daily soil water surplus is the major output with their annual trends, being analysed because of their harmful effects on crop harvests and floods. Soil water surplus trends were analysed founding positive trends, although only two stations were statistically significant at probability level of 95%. ...

Towards an understanding of the effect of road pollution on adjacent food crops: Zea mays as an example
This work is a preliminary study to test the hypothesis that major roads can have an adverse effect on the heavy metal composition of soil and food crops. Surface and subsurface soil samples were collected at increasing distances from the major road in the Araxos area and they were analysed for organic C, Al, Pb, Cd, Zn, Cu, Ni, Fe, Mn, Cr, Co, P, Ca, Mg and Na by inductively coupled plasma ...

Survey of lanthanoids in plants from a tropical region
Several anthropogenic sources may provide lanthanoids (La, Ce, Nd, Sm, Eu, Tb and Yb) to the agricultural and forestry landscapes. Because little information is available on the distribution of these chemical elements in Brazilian tropical ecosystems, this work focuses on the survey in leaves of diverse plant species (native trees, epiphytes and crops) from different ecosystems. Soil under crown ...
