Abstract High concentrations of B and Se found in some arid environments are detrimental to sustainable agriculture. Vegetation management may be a remediation strategy designed reduce soil nontoxic levels. Two separate field experiments were conducted study uptake four different plant species grown containing high (water‐extractable ranging from 1–10 mg kg −1 soil) (total 0.1–1.2 soil). The Brassica juncea L. Czern Coss (Indian mustard), Festuca arundinacea Schreb cv. Fawn (tall fescue),...
The purpose here is to reexamine the ecological importance of dew in arid and semiarid regions with a focus on eastern Mediterranean area. This reevaluation particular under controversial perspective that insufficient as source water for plants but sufficient promote spread plant diseases. Adana, Turkey, was selected an appropriate test ground well‐documented meteorological data newly developed photosynthesis transpiration rate monitor (PTM), which used detect response presence leaves. A...
Bioorganic fertilizers can alleviate (a) biotic stresses and sustainably increase crop yields. The effect of bioorganic on the rhizosphere bacterial community Panax notoginseng soil metabolism remains unknown. Here, we tracked changes in physicochemical properties, microbiota responses, metabolic functions after addition a fertilizer P. field. application reduced acidification, improved organic matter, increased contents total/available nutrients. Soil amendment with significantly affected...
Four temperature treatments were studied in the climate controlled growth chambers of Georgia Envirotron: 25/20, 30/25, 35/30, and 40/35 °C during 14/10 h light/dark cycle. For first stage (V3-5), highest net photosynthetic rate (P N) sweet corn was found for lowest 28-34 µmol m-2 s-1 while P N treatment 50-60 % lower. We detected a gradual decline about 1 unit per increase temperature. Maximum transpiration (E) fluctuated between 0.36 0.54 mm h-1 (≈5.0-6.5 d-1) high minimum E 0.25 (≈3.5-5.0...
Soil evaporation process can be divided into three stages: the constant‐rate, falling‐rate, and low‐rate stages. surface temperature is closely related to soil rate stage. The objectives of this study were: (i) propose an approach determine stage by using infrared (IR) radiometers, three‐temperature (3T) model, Priestley–Taylor (PT) model; (ii) test it on types (coarse sand, clay), (iii) apply remote sensing. A drying experiment address these was continuously performed for 539 h at constant...
ABSTRACT Only a small fraction of the transition metals content in sludge‐amended soils is soluble, and yet this major contributor to mobility bioavailability metals. The chemical species zinc (Zn) copper (Cu) soluble fractions soil–sludge mixtures were characterized with respect their charge, molecular weight, stoichiometry using ion exchange resin gel chromatography procedures. change metals' time after sludge application was followed for 100 d. Copper water extracts sludge–sand found...
Abstract Infiltration from a point trickle source in the presence of water extraction is investigated using an approximate hemispherical model. Analytic expressions for position wetting front are derived. In short‐time limit follows simple t 1/3 dependence. The rate advance depends on single soil parameter, closely related to saturated content. At larger times effects modify solution exponential approach limiting radius, which determined by balance between competing discharge and processes....
Abstract Numerical and analytical solutions for water flow from a point source are compared. The numerical solution was the nonlinear moisture equation corresponding linearized form. For cyclic conditions, results were approximately same with regard to range in values between wettest driest values. However, show faster response both wetting drying. Computational times required of order 1/20 1/200th that finite difference solutions.
A method is described to estimate daily soil water evaporation from a drying uniform bare soil. The involves wind speeds (u) and midday infrared thermometric measurements of surface temperatures the (Td) nearby reference dry (To). Calculation made using linear function (To-Td) u derived basic energy balance considerations. An experiment was conducted in Tucson, Ariz., compare lysimeter-measured values with those estimated on basis method. Three lysimeters (0.5 by 0.5 0.12 m) containing were...
Abstract Tomatoes and cucumbers were irrigated by sprinkling trickling, using equal quantities of water containing 800 mg Cl/liter having an electrical conductivity 3.6 mmho/cm. Sprinkling produced higher contents soluble diffusible ions, free ammonia, amino acids in the leaves, reduced starch, protein, pigments, relative turgidity. The yield ‘Moneymaker’ tomatoes trickling was more than double that obtained sprinkling, while no at all achieved from sprinkled ‘Marmande’ cucumbers....
Evaporation of soil water is a major balance component during early growth stages irrigated field crops, row crops with incomplete cover, and in soils high table. Quantification evaporation can help environmental irrigation management. The objective to develop new method estimate daily using differential measurements temperature. A advantage this approach that sensible heat flux be replaced by those surface An empirical coefficient was determined from integrated energy fluxes over daytime...
ABSTRACT When heat-acclimated pigeons are exposed to ambient temperatures of 50–60°C, extremely high cutaneous evaporative cooling, together with a insulative capacity the feather coat, creates for bird microclimate within which physiological processes can be regulated normally. By skillfully using this cooling garment, maintain their resting metabolic rate and regulate low skin body temperatures, employing neither panting nor gular fluttering. These achievements parallel those arctic...
The effect of atmospheric water vapor (AV) on plants has mostly been neglected in climate impact studies. objectives this study were to determine the AV photosynthesis (Pn), dry matter production (DM), transpiration (Tr), leaf conductance (gl) and use efficiency (WUE), controlled chambers. relative humidity (RH) was held near 30, 60, 85%. DM WUE increased with RH. δDM/δRH ~ 0.3 from 30% 60% ~2.2 85%, δWUE/δRH ~0.2 for all RH's. improved at a rate 0.2 units each percent RH resulted synergy...
