Regional P stocks in soil and in animal manure as compared to P requirement of plants in Finland

20 January 2014

Phosphorus (P) is an essential plant nutrient and sufficient availability is sustained by soil reserves and fertilization.

Plant Requirement and Zero Balance – Soil P Development under Two P Input Scenarios in Finland

20 January 2014

Phosphorus (P) loading to watercourses is clearly related to soil P status (STP), which has more than doubled in Finland since 1950s due to positive P balances.

Case Studies of Present vs. Optimum P Use and Respective Development of Soil Test P at Selected Fields on Private Farms

20 January 2014

In Finland about half of the cultivated fields have such high soil test P (STP) concentrations that P fertilization does not give yield increases and could be omitted for several years.

Comparison and Inter-Calibration of Different Soil P Tests Used in the Baltic Sea Countries

20 January 2014

In the countries of the Baltic Sea Region, different standard methods are currently applied to determine the amounts of available P in soils.

Final Report of WP4 “Standardisation of Manure Types with Focus on Phosphorus”

20 January 2014

Phosphorus is a limited essential plant nutrient, a nonrenewable resource and high concentrations of P in surface waters are a major cause of eutrophication.

Database of Hedley fractionation for manures

03 January 2014

Samples of manure and feces were extracted according to modified Hedley fractionation scheme (Sharpley and Moyer, 2001).

Solubility and plant-availability of P in manure

03 January 2014

Manure is a significant source of phosphorus (P), and its P content is nowadays more than what is sold as mineral fertilizer in Finland.

Phosphorus status of agricultural soils in Estonia

03 January 2014

The use of fertilizers increased in the 1960s to the 1980s in Estonia. In the 1990s, the use of mineral fertilizers dropped very sharply and availability of manure has decreased 3–4-fold.

Report on Scenarios for the Optimisation of Nutrient Input and Reduction of Pollutant Loads by Fertiliser Managements with Processed and Untreated Manure

02 January 2014

Manure can be polluted with heavy metals and other contaminants such as organic substances or pathogens. It is a threat for food safety, because these pollutants can be incorporated by the crops.

Database Soil

23 December 2013

The small-scale spatial variability of the easily-soluble P in agricultural soils is related among others to soil type and fertilisation practices.

Database Manure and Manure Products

23 December 2013

The elemental composition, P-solubility and heavy metal content of manure and manure-based products was characterised in order to assess their suitability as fertiliser materials.

Guideline Catalogue for a Sustainable Use of Manure and Manure-Based Fertiliser Products for Farmers

14 November 2013

The imbalanced application of mineral P-fertilisers and P-rich organic sources often leads to massive P-surpluses in agricultural soils. Such excessive loads significantly increase the risk of P-losses which are one major contributor to the eutrophication of water bodies.

Description Sheets of Analysed Manure-Based Products According to Current EU Regulations on Fertilisers

07 January 2013

To sell a product as a fertiliser in Germany or within the EU member states it has to meet the legal requirements of the national or EU-fertiliser law.

Phosphorus acquisition by barley (Hordeum vulgare L.) at suboptimal soil temperature

20 December 2012

We studied the effects of soil temperature (8 ºC and 15 ºC) on barley growth, barley phosphorus (P) uptake and soil P solubility. Barley was grown in a pot experiment in two soils with different P fertilization histories for 22 year

Prototype model for the phosphorus turnover in soils (P-Engine) in relation to varying environmental conditions in the Baltic Sea Region

05 December 2012

One important precondition to close anthropogenic P-cycles and to reduce undesired nutrient inputs into the Baltic Sea is the complete utilisation of fertiliser P applied to agricultural soils
