Abstract:

Soil samples were collected from 14 long-term field experiments in south-western Australia to which several amounts of superphosphate or phosphate rock had been applied in a previous year. The samples were analysed for phosphorus (P) by the Colwell sodium bicarbonate procedure, presently used in Western Australia, and the Mehlich 3 procedure, being assessed as a new multi-element test for the region. For the Mehlich procedure, the concentration of total and inorganic P in the extract solution was measured. The soil test values were related to yields of crops and pasture measured later on in th

Abstract:

The Mehlich-l (double-acid) soil test extractant is used widely on sandy soils in the southeastern United States. Research with eight major vegetables in Florida showed that the Mehlich-1 solution for phosphorus was correlated with crop yield and quality responses. Soils with a Mehlich-1 index for phosphorus greater than 30 mg·kg-1 required no phosphorus fertilization. Crop responses were not highly correlated with Mehlich-1 potassium index and it was difficult to predict crop response to potassium fertilization. The lack of predictive capability of the Mehlich-1 extractant for potassium raise

Abstract:

Recent changes in soil testing methodology, the important role of P fertilization in early establishment and soil coverage, and new restrictions on P applications to turf suggest a need for soil test calibration research on Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb), and perennial ryegrass (Lolium perenne L.). Greenhouse and field studies were conducted for 42 days to examine the relationship between soil test P levels and P needs for rapid grass establishment using 23 NJ soils with a Mehlich-3 extractable P ranging from 6 to 1238 mg·kg–1.

Abstract:

Increasing concern for the amount of P entering lakes in Manitoba may lead to regulation of P concentration in agricultural soils. A possible means for this regulation is the use of soil test P. This may require a means of comparing soil test P analyses as various laboratories in Manitoba employ different methods of soil test P determination. Thus, the objectives of this study were to (i) compare the methods of P determination in Manitoba soils, and (ii) develop equations for converting different soil test P methods from one to another.

Vegetable P fertilization recommendations in Florida are based on a soil test using the Mehlich-I (double-acid) extractant. For several Florida vegetables, including watermelon, there is a lack of crop correlation and extractant calibration data. Phosphorus fertilizer studies were conducted on sites with soils ranging in Mehlich-I P indices from 4 to 30 mg·kg-1. There was a quadratic yield response on soils testing 4 mg·kg-1 P with yield maximizing at about 70 kg·ha-1 fertilizer P. Watermelon did not respond to P additions on soils testing greater than 30 mg·kg-1 of Mehlich-I P.

Abstract:

Yield responses of `Blue Vantage' cabbage (Brassica oleracea L.) to P fertilizer and two commercially available biostimulants—ROOTS and ESSENTIAL-were evaluated on soils very high in P fertility. Head yield was not increased with P fertilizer when cabbage was transplanted into soil with Mehlich-3 soil test P indexes ≥ 112 ppm (112 mg·kg-1). Neither of the biostimlants applied as a root drench at transplanting influenced head yield or plant tissue nutrient analysis.

Abstract:

In this paper we present the soil test P saturation, budget, and fractionation procedures used in R. R. Simard’s laboratory. We expand that work to: (1) Mehlich-III P saturation index using a weighting factor for Fe accumulation in soils; (2) P budget including below-ground biomass; and (3) compositional data analysis of P fractions to describe changing patterns of soil P fractions that differ in their availability to plants and risk to the environment. The Mehlich III P and Al two-way classification applied to forage crops by Simard and co-workers was replaced by the P/Al ratio test for P fer

Abstract:

The aim of the paper was to test the universality of three multi-nutrient soil tests after a radical intervention in soil chemistry by gypsum treatment on a variable set of 36 soils. Pot experiments with barley in a growth chamber were conducted to determine the bioavailability of K, Mg, P, Mn and B from soils. There were no marked differences in correlations between soil tests and the plant in K, Mg and P. But in the case of Mn and B Mehlich 3 test was not in appropriate agreement with the plant. Shortcoming of water extraction is missing information of capacity character for the derivation o

The objective of the study was to examine a possibility of predicting phosphorus leaching from the top layer of agricultural soils by rainfall simulations by means of three multi-nutrient soil tests: Mehlich 3, NH<sub>4</sub>-acetate extraction and water extraction (1:5, w/v). Another objective was to determine parameters of maximum phosphorus losses after an extreme load of rainfall on the top layer. Forty soils from different localities of the Czech Republic were used for the experiment. A leaching experiment was conducted in pedological cylinders with a soil layer of about 1 cm

Abstract:

The phosphorus (P) status of 535 surface soils from all states of Australia was assessed using the following soil P tests: Colwell-P (0.5 m NaHCO3), Olsen-P (0.5 m NaHCO3), BSES-P (0.005 m H2SO4), and Mehlich 3-P (0.2 m CH3COOH + 0.25 m NH4NO3 + 0.015 m NH4F + 0.013 m HNO3 + 0.001 m EDTA). Results were correlated with soil P assays selected to estimate the following: soil solution P concentration (i.e. 0.01 m CaCl2 extractable P; Colwell-P/P buffer index); rate of P supply to the soil solution (i.e. P released to FeO-impregnated filter paper); sorbed P (i.e. Colwell-P); mineral P (i.e. fertili

The objectives of this study were to evaluate the Cd availability and accumulation in soil, transfer rate and toxicity in lettuce and rice plants grown in a Cd-contaminated Typic Hapludox. Two simultaneous greenhouse experiments with lettuce and rice test plants were conducted in a randomized complete block design with four replications.

Phosphorus application significantly (P< 0.05) increased total tuber yield at 16 sites. The mean relative yield for these responsive sites was 69.7% (range 37.4- 91.2%) compa

The objective of this research was to determine the critical level of P for big red chili in Java Island. Soil samples were collected from 19 locations in Java Island. The soil P before planting of 19 locations was determined by three methods of P extraction namely Bray 1, Olsen, and Mehlich III.

Phosphorus (P)-containing starter fertilizers are often recommended for establishing new turf, regardless of P levels indicated by the soil test. However, few field studies have been conducted to determine the effects of P in starter fertilizer on the rate of turf establishment. The primary objective of this study was to determine if P in starter fertilizer enhances tall fescue groundcover and growth during establishment on silt loam soil. This 2-year field study was conducted on silt loam soil tilled with a rototiller or core-aerated and vertically sliced. Mehlich-3 P levels ranged from 38 to

Soil phosphorus (P), which is potentially a risk for environmental contamination, is currently interpreted using soil P saturation in North America. Our objective was to assess the ratio of P to aluminum (Al) in the Mehlich-III (M-III) soil test to build P requirement models for corn and soybean. We analyzed 129 corn and 19 soybean P fertilizer trials. For corn, the (P/Al)M-III ratio improved soil fertility classification compared with PM-III alone. The critical PM-III value as determined by the Cate-Nelson procedure was found to be 31.5 mg PM-III kg-1, close to published values. The critical

Surface (0–20 cm) and subsoil (20–40 cm) samples were collected after harvest from 1984 to 1993 on a Chicot sandy clay loam soil (Grey Brown Luvisol) fertilized with two rates of inorganic P and K and with dairy manure.
