Free soil testing for accurate fertiliser application
With the growing season nearly upon us, Welsh farmers are being given an opportunity to discover the benefits of soil analysis through a number of free soil testing workshops at Farming Connect. Regular soil testing enables farmers to adopt a targeted approach to fertiliser use, thus providing significant cost savings, according to Lisa Roberts of Farming Connect. Soil analysis also identifies ...

High-Yielding corn response to applied Phosphorus, Potassium, and Sulfur in Nebraska
Nutrient management recommendations may change as yield levels and efficiency of crop production increase. Recommendations for P, K, and S were evaluated using results from 34 irrigated corn (Zea mays L.) trials conducted in diverse situations across Nebraska. The mean yield was 14.7 Mg ha–1 with adequate fertilizer applied. The median harvest index values were 0.52, 0.89, 0.15, and 0.56 for ...

Evaluation of zone soil sampling approaches for phosphorus and potassium based on corn and soybean response to fertilization
Soil sampling approaches have been compared based on soil-test variation. This study evaluated sampling approaches for P and K based on yield response to fertilization. Strip trials were established on four fields for P and three fields for K managed with corn (Zea mays L.) and soybean (Glycine max L. Merr.) rotations and evaluated 3 or 4 yr (27 site-years). Treatments replicated three to four ...

Spring wheat and durum yield and disease responses to copper fertilization of mineral soils
Copper deficiency has been linked to the incidence of a number of wheat diseases. Canadian research on mineral soils has suggested that low Cu availability, as indicated in a DTPA extraction soil test, combined with low soil organic C and coarse textures may also result in Cu deficiency of cereals. The objective of this study was to determine the yield responses of spring wheat (Triticum aestivum ...

OCP Kenya School Laboratories (OSL Project) - Case Study
The success of the OCP Kenya-OCP School Lab (OSL) project stems from a comprehensive approach to addressing agricultural challenges in Kenya. A review of various surveys on the state of agriculture revealed a connection between low crop yields, reduced incomes, and soil fertility constraints, particularly soil acidity. Additionally, a lack of awareness about soil health and fertility ...

Agronomically Speaking: Fall Fertility? From Soil Test to Prescriptions
Farmers understand that soil fertility is a key component of growing healthy and high yielding crops. While there is much debate on how we accomplish soil fertility and health, there are some general items that are helpful to remember. However, because it was an extremely wet year for many across the country it is even more important to soil test this year. Some of the nutrients ...

Advantages of soil nutrient testing equipment in field management
Soil nutrient testing equipment has revolutionized the field of agricultural management. These devices provide farmers and gardeners with accurate insights into the nutrient levels in their soil, enabling them to make informed decisions about fertilization and irrigation. In this essay, we will explore the advantages of soil nutrient testing equipment in field management. Accurate nutrient ...

Leaf Cares Article - Foliar Analysis
What is Leaf tissue testing? Leaf tissue testing is a crucial process for evaluating the concentration of essential elements within plant tissue. Essential nutrients, categorised as micronutrients and macronutrients, play key roles in sustaining the plant’s life cycle. Micronutrients, required in smaller amounts and macronutrients needed in larger amounts are essential for achieving ...

Spatial variability of the Illinois soil nitrogen test: Implications for sampling in a turfgrass system
Nitrogen fertilization of turfgrass continues to be scrutinized due to environmental concerns. Practices that reduce fertilizer inputs without sacrificing turfgrass quality are needed, but a reliable test of N status in turfgrass is not currently available. The Illinois soil N test has been developed to predict crop response to applied N by measuring the amount of amino sugar N in the soil. Amino ...

A partial budget analysis for phosphorus-based nutrient management plans for Connecticut dairy farms
This study estimated changes in costs of manure handling, costs of the fertilizer replacement value of manure, and expected changes in net revenues associated with the implementation of manure nutrient management plans (NMPs) based on the agronomic critical concentration for P using a partial budget analysis. The net revenue from manure management practices traditionally used by farmers in a ...

Glyphosate and AMPA chronic risk assessment for soil biota
Glyphosate is a broad‐spectrum herbicide used widely in agriculture, horticulture, private gardens and in public infrastructure, where it is applied to areas such as road sides, railway tracks and parks to control the growth of weeds. The exposure risk from glyphosate and the primary soil metabolite aminomethylphosphonic acid (AMPA) on representative species of earthworms, springtails, ...

Phosphorus runoff from turfgrass as affected by phosphorus fertilization and clipping management
Received for publication December 8, 2008. Phosphorus enrichment of surface water is a concern in many urban watersheds. A 3-yr study on a silt loam soil with 5% slope and high soil test P (27 mg kg–1 Bray P1) was conducted to evaluate P fertilization and clipping management effects on P runoff from turfgrass (Poa pratensis L.) under frozen and nonfrozen conditions. Four fertilizer treatments ...

Linking Wisconsin dairy and grain farms via manure transfer for corn production
One relatively under-used manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of an effort to link grain and livestock farms in southern Wisconsin, 20 on-farm trials were ...

Direct steam distillation as an alternative to the illinois soil nitrogen test
Development of the Illinois Soil N Test (ISNT) has rejuvenated the search for a soil-based N test to measure potentially mineralizable soil N. Accurate quantification of amino sugar N has been achieved using the ISNT, but issues concerning sample variability and analysis time have led to the discovery of a 10 mol L–1 NaOH direct steam distillation (DSD) procedure. Our primary objective was to ...

Performance of an optimized nutrient management system for double-cropped wheat-maize rotations in North-Central China
Overapplication of N and P and insufficient supply of K are considered primary reasons for restriction of yield improvement in the North China Plain. Optimized nutrient management practices based on soil testing and yield targets have been developed. Other large scale field experiments have indicated that additional improvement for yield and nutrient use benefits is needed. The objective of this ...

Recent mechanical cultivation of lawns enhances lime application efficacy
While the relationship between soil acidity and thatch accumulation in maintained lawns has been reported, interacting effects of cultivation and surface lime applications on soil acidity have not. The experimental objective was to determine how antecedent mechanical cultivation of mature turfgrasses interacts with surface application of liming agents to neutralize soil acidity within the upper ...

Determining phosphorus and sediment release rates from five irish tillage soils
Received for publication December 11, 2008. The aim of this study was to compare the nutrient and sediment releases from five Irish tillage soils, inclined at 10- and 15-degree slopes, under a simulated rainfall intensity of 30mmh–1 in a controlled laboratory study. Using the relationship between soil test phosphorus (STP) in the five soils and the dissolved reactive phosphorus (DRP) released in ...
