Soil amendments are the substances that applied to or mixed into the topsoil to improve physical, chemical and biological properties of soil and plant growth. They can improve soil fertility, promote the growth and reproduction of microorganisms in the soil, improve the agricultural productivity of soil and improve the environment for plant growth. Using soil amendment is an important solution ...
Soil moisture sensor is an important tool in modern agriculture and horticulture. These devices measure the amount of water present in the soil, an important parameter in managing irrigation and ensuring that plants get the right amount of water.In this article, we will discuss the different types of soil moisture sensors, how they work, and their applications in agriculture and horticulture.Type ...
Late spring (late April to early June) is an important time in almond orchard development. During this time, the almond embryo is developing into a mature kernel. At this point in the season, proper irrigation management can be a major contributor to the difference between a marginal and major improvement in crop yield and quality. Development is complete when the kernel fills the shell ...
With irrigation being used in many spheres of life and food production methods getting diversified, it is not surprising that research on this topic is getting more specialized. Procedures for analysis, which were restricted earlier to big institutions, need to be widely available so that their reach is extended and science will benefit from more in-depth studies. An increasing number of ...
Agriculture Victoria has installed several soil moisture probes on a range of soil and pasture types across Victoria. Soil moisture probes have helped with making early decisions in the cropping industry for some time with monthly analysis produced as a newsletter by Dale Boyd. The probes are capacitance enviropro probes manufactured in South Australia and are 80 centimetres long with eight ...
Why Acclima soil moisture sensor technology is superior in terms of accuracy and cost Permittivity is a property of matter and is well characterized especially for materials that are electrically non-conductive. Water in its pure form is non-conductive. Permittivity quantifies the charge holding capacity for insulating materials. It is the ratio of stored electric charge to an applied electric ...
With the pressure to increase food production, every agricultural practice that can be optimized for improving crop yield is under scrutiny; therefore, micronutrients, which are important for crop health and growth, are receiving more attention. Agronomists are increasingly studying different treatment methods to establish the easiest and most cost-effective way to improve micronutrient ...
Analysis of the root system is important in ensuring sustainable crop production, reducing nutrient input and irrigation, and protecting soil carbon pools. Getting rapid and frequent images of what is happening underground can help people make timely decisions about agricultural practices to maintain plant health and ensure the judicious use of resources. Root analysis can reduce financial and ...
Crops, Nutrients, Irrigation & Root Analysis Analysis of the root system is important in ensuring sustainable crop production, reducing nutrient input and irrigation, and protecting soil carbon pools. Getting rapid and frequent images of what is happening underground can help people make timely decisions about agricultural practices to maintain plant health and ensure the judicious use of ...
Introduction You need to get the right amount of water to crops at the right time. Water and nutrients are used most efficiently when your crops have access to the amount of water the crop needs and the soil can hold. This article describes how to use the data provided by soil moisture probes to more effectively manage your farm. Observing and understanding the consequences of soil moisture ...
HydraProbe used to improve water supply forecast from 3 SNOTEL sites in Idaho over traditional antecedent conditions using the principle component forecast model Much of the water in the Western United States used for irrigation, municipal supplies and hydro-electric production originates as winter snow pack at higher elevations. Since the early 1900s, the correlation between ...
Actual daily evapotranspiration (ETa) was measured in two weighing micro-lysimeters, from 1 July 2009 to 30 June 2011 on an alpine meadow in the Qilian Mountains, northwest China. The findings showed that the mean daily ETa in the unfrozen and frozen periods was 2.0 mm and 0.2 mm, respectively. The dominant factor affecting ETa in the unfrozen period was net radiation (RN), whereas those in ...
The calibration and validation of remotely sensed soil moisture products relies upon an accurate source of ground truth data. The primary method of providing this ground truth is to conduct intensive field campaigns with manual surface soil moisture sampling measurements, which utilize gravimetric sampling, soil moisture probes, or both, to estimate the volumetric soil water content. Soil ...
In the Huaibei Plain basin, China, soybean is a main crop. During the soybean growth period, rainfall can vary largely and depth to watertable can also vary largely. The amount of water supplied to the soybean rootzone by groundwater affects soybean growth and yield. Accurate simulation of groundwater contributions to soybean rootzone soil moisture (groundwater contribution) can be important ...
The objective of this study was to evaluate the performance of the FAO-AquaCrop model in winter wheat in the southern Loess Plateau of China. Multi-year field experimental data from 2004 and 2011 were used to calibrate and validate the model for simulating biomass, canopy cover (CC), soil water content, and grain yield under rainfed conditions. The model performance was evaluated using root ...
Agricultural Research Service researchers in Bushland, Texas, are helping farmers make the most of their water supplies in a region where they depend on the Ogallala Aquifer, a massive underground reservoir under constant threat of overuse. Steve Evett, Susan O'Shaughnessy, and their colleagues at the Conservation and Production Research Laboratory are developing and testing soil-water and ...
The Stevens pF Sensor is a unique matric potential probe, which is used to measure the soil water potential of a soil - the force with which water is held within the soil and how much energy is needed to overcome this force to extract water from the soil. Unlike traditional tensiometers such as gypsum blocks, the Stevens pF Sensor utilizes a patented heating element to measure soil water ...
Abstract Irrigation water management has to do with the appropriate application of water to soils, in terms of amounts, rates, and timing to satisfy crop water demands while protecting the soil and water resources from degradation. In this regard, sensors can be used to monitor the soil water status; and some can be used to calculate irrigation amounts and to decide when to optimally irrigate. ...
A simple water balance model was used to calculate soil water reserve in a Mediterranean forested catchment. The relationship between soil water reserve and leaf water potential and stem water content was analysed. The usefulness of these variables as plant water status indicators was tested. The analyses were developed with a seven-year-long database (2001–2007) in the case of soil water content ...
Abstract Irrigation water management practices could greatly benefit from using soil moisture sensors that accurately measure soil water content or potential. Therefore, an assessment on soil moisture sensor reading accuracy is important. In this study, a performance evaluation of selected sensor calibration was performed considering factory- laboratory- and field-based calibrations. The selected ...
