Some Experiments on Restrained Shrinkage of Clays Undergoing Drying
This paper describes engineering applications which show the engineering significance of testing the phase composition of soils, including determining the level of water saturation. It further explains why, in order to accurately model in situ conditions in soil deposits, it is necessary to test the phase composition of soil under conditions of horizontal restraint and changing moisture content. ...

Conversion to extensive grassland
The Mitigation Strategy of the measure Conversion to extensive grassland refers to flood prevention and environmental protection also. Flood protection can be achieved by: Increase the infiltration of rainwater by high roughness and preventing soil silting; Reducing the flow velocity of surface run off; The hydrologic-hydraulic effect varies depending on the vegetation, soil condition at ...

Shifts in plant nutrient use strategies under secondary forest succession
Abstract In evergreen broad-leaved forests (EBLFs) in Tiantong National Forest Park, Eastern China, we studied the soil chemistry and plant leaf nutrient concentration along a chronosequence of secondary forest succession. Soil total N, P and leaf N, P concentration of the most abundant plant species increased with forest succession. We further examined leaf lifespan, leaf nutrient ...

Defense characteristics of seral deciduous broad-leaved tree seedlings grown under differing levels of CO2 and nitrogen
Mixed broad-leaved forests are abundantly populated by several kinds of herbivore species in northern Japan. The life of herbivores depends strongly on the quality of food leaves. Leaf quality is changing with increasing atmospheric CO2 and nitrogen deposition. Four seral species of deciduous broad-leaved tree seedlings (alder, birch, oak and maple) were raised in all four combinations of two ...

Soil tensiometer
What is a soil tensimeter? Soil tensimeter uses the principle of negative pressure to measure soil moisture and studies soil moisture movement from the perspective of energy. Transparent PVC pipe can clearly see the amount of water, low-end with high-quality clay head, fast sealing, accurate measurement. Soil tensiometer is a practical method to measure soil condition by using a negative pressure ...

The Behavior at the Shrinkage Limit of Clay Undergoing Drying
In this paper, possible links between the shrinkage limit and distinct changes in other properties of a clay soil undergoing drying are discussed. These properties include the volumetric air content of the soil, the heat of wetting, the tensile strength, the total suction, and the thermal resistivity of the soil. The distinct changes are of interest in themselves, and possible explanations for ...

Benefits of Integrated Soil Sensor:
An integrated soil sensor is a device that measures various soil parameters such as soil moisture, temperature, pH level, and nutrient levels in real-time. The sensor is embedded into the soil to provide continuous data on the soil conditions, allowing farmers and researchers to make informed decisions about their crops and soil management practices.The need for an integrated soil sensor arises ...

Relationship between light and heavy fractions of organic matter for several agricultural soils in China
Although numerous studies about the nature and turnover of soil organic matter (SOM) in light and heavy fractions (LFOM and HFOM, respectively) have been made, little information is available in relation to the relationship between LFOM and HFOM, and no attempts have been made to quantify a general relationship between LFOM and HFOM for agricultural soils under field condition. Our hypothesis is ...

Relationship between root characteristics of peanut in hydroponics and pot studies
A large root system can be an important character for drought tolerance. Measuring root characteristics in soil medium is tedious, time consuming, and labor intensive. The objective of this study was to determine the association between root characteristics of peanut (Arachis hypogaea L.) grown in hydroponics and in pot experiments. Twelve peanut genotypes were planted in a randomized complete ...

Accumulation of weathered p,p′‐DDTs in hybridized Cucurbita pepo cultivars
Cucurbita pepo spp pepo (zucchini) is known as an exceptional weathered dichlorodiphenyldichloroethylene (DDE) accumulator, whereas Cucurbita pepo ssp ovifera (squash) is termed a nonaccumulator. Experiments were conducted with hybridized zucchini and squash to assess the inheritance pattern of DDX (the sum of p,p′‐dichlorodiphenyltrichloroethane [p,p′‐DDT], p,p′‐dichlorodiphenyldichloroethane ...

Potassium and winter hardiness
The role of Potassium in metabolic processes such as protein synthesis and the movement of sugars within the plant is now well understood and recognised as crucial for maximising quality and yield. But it is now known Potassium also plays a significant role in helping crops resist disease and environmental stresses during winter dormancy and ensuring optimum supplies of Potassium to see crops ...

Agronomic performance of different pea cultivars under various sowing periods and contrasting soil structures
Yield variability of spring pea (Pisum sativum L.) in farmers' fields is mainly due to soil compaction at sowing and abiotic stresses during the reproductive period. Winter peas flower earlier, and thus should be less sensitive to abiotic stress at the end of the cycle, but because of their sensitivity to frost they must be sown late in autumn when soils are very wet. Pea breeders are working on ...

Database “organic and mineral residues”
In the spirit of the material recycling concept in Germany (KrW-/AbfG, 1994), wastes are to be recycled as completely as possible, avoiding any impairment for mankind and the environment. In this connection, avoidance of material burdens by excessive nutrient and pollutant discharge is particularly important in the treatment, recycling and bringing into circulation of waste materials for re-use ...

Effects of biowaste compost on vegetative growth, Yield and fruit quality of james grieve apples
In Lower Austria 69 agricultural composting plants are in operation in addition to municipal and commercial composting plants. The agricultural composting plants process separately collected organic household waste as contractual partners for the neighbouring municipalities. The compost produced is used to a large extent on the agricultural fields of the plants' owners. In order to improve the ...

SureForce VS. Springs in No-Till and Conventional Till
SureForce is a hydraulic downforce and uplift system that automatically adjusts the right amount of force on each row to achieve optimum and uniform seed depth in the field. While the optimum depth for corn is generally universal no matter where you are located, your ground and farming practices can make a big difference in what you need to do to achieve that depth – especially tillage ...

Kinetic distribution of 14C-Metsulfuron-Methyl residues in paddy soils under different moisture conditions
Rice paddy soils undergo several cycles of drying and wetting during a growing season. A laboratory study was conducted to determine the effect of soil moisture conditions on the distribution and kinetics of extractable and bound residues of 14C-metsulfuron-methyl in six Chinese paddy soils during 84 d of incubation at 15°C with moisture contents varying from 20 to 50% of the field water-holding ...

Detecting plant root diseases & pests
Soil-borne pests and diseases are harder to detect than those on the aerial parts of a plant. Visible symptoms in leaves and stem appear only in the final stages of the attacks. If plants are treated at this point, it may be difficult to avoid plant injury, as plants could already have been severely impacted. Early detection and identification are key to prevent crop loss. There are, however, ...
