A rainfall simulation study on the relationships between soil test P versus dissolved and potentially bioavailable particulate phosphorus forms in runoff [PDF]

open access: yes, 2005
Runoff from clayey soils often contains abundant particulate phoshorus (PP), part of which may solubilize in surface waters. Monitoring losses of potentially bioavailable forms of PP is expensive, calling for other ways to predict them.

Phosphorus Availability and Spring Barley Yields Under Graded P-Doses in a Pot Experiment

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2018
The pot experiment with graded P doses was carried out in 2015 and 2016 in the Crop Research Institute, Prague – Ruzyně (undermentioned CRI). Three soil types were chosen for the experiment – Chernozem, Cambisol, Haplic Luvisol. The soils were treated by

Targeting phosphorus loss with carbon farming practices? Results from an on‐farm study

open access: yesJournal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract Agricultural soils lose P to waterbodies and C to the atmosphere. Reversing the C trend requires change in management (carbon farming), but what is the effect of carbon farming practices on P transport from soils to waterbodies? This was empirically studied by analyzing the P loss risks from 20 farms participating in a 5‐year on‐farm carbon ...

Enhancing soil health through no‐till, cover crops, and compost: A 5‐year field study

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract The capacity of soil management systems to conserve and promote soil health is crucial for its sustainability. While the effects of individual soil management practices on soil health receive considerable attention, their combined effects remain understudied. This paper presents the results of a 5‐year field experiment designed to evaluate the

Determination of plant-available micronutrients by the Mehlich 3 soil extractant - a proposal of critical values

open access: yesPlant, Soil and Environment, 2016
Soil testing in the Czech Republic is based on the use of the Mehlich 3 method for determination of macronutrients and diethylentriaminepentaacetic acid (DTPA) and hot-water extraction for determination of micronutrients. Since inductively coupled plasma

Micronutrients for cacao: Availability classes in two soil layers

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Efficient management of soil micronutrients is crucial for the yield and sustainability of cacao (Theobroma cacao L.), especially in tropical regions. However, specific availability classes for copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn), extracted by Mehlich‐1, had not yet been established for the crop in Brazil. This study presents,

Glomalin production in Atlantic Forest: Effects of soil properties and plant families

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Glomalin, a glycoprotein produced by arbuscular mycorrhizal fungi (AMF), contributes to soil aggregation, carbon sequestration, and nutrient cycling. We present the first comprehensive assessment of environmental factors associated with glomalin availability, measured as easily extractable (easily extractable glomalin‐related soil protein [EE ...
