Boron deficiency responses in maize (Zea mays L.) roots

Journal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Determination of available soil phosphorus by chemical methods

Agricultural and Food Science, 1978
Phosphorus uptake by oats in pot experiments was compared with phosphorus test values obtained for experimental soils. Phosphorus was extracted from the soil using acid ammonium acetate solution, Bray 1 solution, Olsen solution, ammonium fluoride ...

Communities of Arbuscular Mycorrhizal Fungi in the Roots of Pyrus pyrifolia var. culta (Japanese Pear) in Orchards with Variable Amounts of Soil-Available Phosphorus

Microbes and Environments, 2012
We examined the colonization rate and communities of arbuscular mycorrhizal fungi (AMF) in the roots of Pyrus pyrifolia var. culta (Japanese pear) in orchards to investigate the effect of phosphorus (P) fertilization on AMF.

Climate Change Mitigation in the Dairy Sector: Uncovering Heterogeneity Through Eco‐Efficiency Clubs

Agribusiness, EarlyView.
ABSTRACT Combining climate change goals with economic targets is crucial for the dairy sector, which is a significant contributor to agricultural greenhouse gas (GHG) emissions worldwide. In this paper, we assess economic and climate change implications of dairy production with panel data of Irish dairy farms from 2013 to 2021.

The Quantitative Estimate of Bioavailable Inorganic Phosphorus Content in Forest Soils by the Modification of the Anion-Exchange Resin Method

Soil and Water Research, 2006
The anion-exchange resin (AER) method for the estimation of bioavailable phosphorus was slightly optimised for soils with high contents of readily soluble organic compounds as well as for those having very dif­ferent clay and sand contents.

The effect of different rates and forms of sulphur applied on changes of soil agrochemical properties

Plant, Soil and Environment, 2008
A three-year field experiment was conducted from 2000 to 2002 in North-East Poland. Each year three sulphur fertilization rates in the form of sulphate (S-SO2-4) and pure (S-S0) sulphur were applied: 40, 80 and 120 kg/ha. In the soil horizon at the depth
