The procedure for applying phosphorus (P) fertilizer to soil can be divided into three consecutive steps: (i) Measurement of soil-P availability, (ii) calibration of the soil-P fertility level and (iii) estimation of the recommended P dose. Informati

Rice cvs with better hardpan penetration would be expected to be more drought resistant in the rainfed lowlands. Although laboratory methods to facilitate the identification or breeding of cvs with good root-penetration ability have been described, t

Roots of 3-d-old pea seedlings (Pisum sativum L.) were mechanically impeded using a sand core apparatus, which allowed mechanical impedance to be varied independently of aeration and water status. Turgor of root cortical cells was then measured using

Winter wheat (Triticum aestivum L., cv Mercia) was grown at Rothamsted over three seasons (1992/94/95) with plant-available soil P (Olsen-P) ranging from very deficient to superoptimal (1–52 mg P/kg; ADAS soil P Index 0–4). Critical Olsen-P for 9
