To achieve optimal grove nutrition, citrus growers must test grove soil before beginning any fertilization program. Standard procedures for sampling, preparing, and analyzing soil should be followed for meaningful interpretations of the test results and accurate recommendations. This new two-page fact sheet, published by the UF/IFAS Department of Soil and Water Sciences, provides illustrated soil sampling procedures and tables to aid in basic interpretation of lab results.

Fertiliser Use

In the area from Taupo to Auckland, and North Island wide, BOP Fertiliser Ltd, Mt Maunganui, supplies some 700 000 t of fertiliser annually. In the years 1994/95, 1995/96 and 1996/97 total fertiliser sales were 668 900, 700 700 and 678 100 respectively. BOP Fertiliser supplied fertiliser to approximately 50% of New Zealand dairy farms. Nitrogen was applied to 91% of dairy farms at an average annual input of 58 kg N/ha. Less than 4% of farms applying N received >200 kg N/ha. Some 23% of dairy farms received less than maintenance P (30 kg/ha). A review of soil fertility levels on dairy farms in 1996/97 using soil test results from the Soil Fertility Service laboratories at Ruakura suggests some 38% of Olsen P values on dairy farms were below optimum (

Field experiments were conducted during 2017 – 2018 to develop fertiliser prescriptions equations (FPEs) through IPNS for the desired yield targets of Chrysanthemum on Udic Haplustalf . The fertilisers prescription equations (FPEs) were developed under NPK alone and under IPNS for the desired yield target of Chrysanthemum by using the basic parameters. The variation observed in the achievement of targets was within the range of ± 10 per cent (90 – 110%) proving the validity of FPEs. Hence, the Inductive cum Targeted yield approach applied to develop fertiliser equations provides a strong basis for maintenance of soil fertility with high productivity and efficient nutrient management in “Precision Farming” for sustainable and enduring Agriculture.

Phosphorus And Potassium

Abstract Soil tests are performed to determine the amount of nutrients available to plants so that fertilizer and lime recommendations can be formulated. In 1951, State soil testing laboratories had numerous extractants for determining phosphorus and potassium. Twenty years later, only 3 extractants each were used for phosphorus and potassium. In the United States, a regional approach produced standardized methods for several of the most common soil testing procedures. These detailed standard methods resulted from identifying procedural causes for variations in soil test results. For example, the amount of nutrient extracted varied by size and shape of extraction vessel and speed and time of shaking. Currently, terminology and expression of soil test results, and a search for a more universal soil extractant, i.e., one that can be used to determine several rather than a single nutrient, are 2 of the main areas of effort.

Interpreting Soil Test Results is a practical reference for those who need to interpret results from laboratory analysis of soil. It has a comprehensive listing of the soil properties relevant to most environmental and natural land resource issues and investigations. The precursor to this book, What Do All the Numbers Mean?, known as The Numbers Book, was widely used and accepted for interpreting soil test results. This new edition has been completely updated and many sections have been expanded, particularly those on acid sulfate soils and soil salinity. It is a handy and straightforward guide to interpretation of the numbers associated with a wide range of soil tests.
