“…Para o N remanescente do milheto, o aproveitamento pelo milho foi pouco superior ao do N da crotalária, porém a quantidade de N no milho proveniente desta gramínea foi menor, em virtude da menor quantidade de N acumulado na sua massa seca inicialmente: 68,5 e 64 kg ha -1 , respectivamente, em 2001 e 2002. Ladd et al (1983) encontraram, também, valores menores do que 5 % de recuperação do N de leguminosas pelo trigo no segundo cultivo. O baixo aproveitamento do N pelo milho no ano agrícola subseqüente deve-se, provavelmente, ao fato de o N remanescente das culturas de cobertura e do fertilizante mineral ser encontrado, predominantemente, sob a forma de compostos orgânicos e sua disponibilidade seguir o padrão de mineralização da MOS (Harris et al, 1994).…”

“…The amount of fertilizer N required for wheat following pea was higher than that of CW in the first rotation cycle and the converse was true for the second cycle (Table 2). This may be due to the cumulative effect of soil N conservation by Nfixing legumes (Ladd et al 1983;Evans et al 1991), and may be enhanced by NT management (later in discussion). Averaged across tillage treatments wheat following the legumes required annually 5 kg N ha -1 less in the second rotation cycle compared to the first, while monoculture wheat required 13 kg ha -1 more N ( Table 2).…”

Soon, Y. K. and Clayton, G. W. 2002. Eight years of crop rotation and tillage effects on crop production and N fertilizer use. Can. J. Soil Sci. 82: 165-172. Although tillage systems and crop rotations can affect crop production and uptake of nutrients, their long-term effects, particularly their interactions, are not well-documented. Therefore, we measured the N, P, and K contents and yields of crops through two rotation cycles, especially wheat (Triticum aestivum L.), of four crop rotations managed under conventional tillage (CT) and no-tillage (NT) systems. The study was conducted 1993 through 2000 on a sandy loam soil in northwestern Alberta, Canada. The four-course crop rotations were: (i) field pea (Pisum sativum L.)-wheat-canola (Brassica rapa L.)-wheat; (ii) red clover (Trifolium pratense L.) green manure-wheat-canola-wheat; (iii) fallow-wheat-canola-wheat, and (iv) continuous wheat (CW). The crops were fertilized using regional recommendations based on soil test results. Previous crop effect on wheat yield was in the order: field pea = red clover green manure > fallow > canola > wheat (CW); it had little influence on N, P or K content in wheat grain or straw. There was no interaction of tillage with crop rotation on wheat production or nutrient content. Tillage treatments affected neither production of other rotation crops nor their nutrient concentrations. During the second rotation cycle, N fertilizer requirement decreased, and wheat yield was 22% higher, under NT as compared to CT. This study showed that (i) field pea is an attractive replacement for red clover green manure; and (ii) recommendations for N from soil test results should factor in the type of tillage system used. )-blé-canola-blé, iii) jachère-blé-canola-blé et iv) monoculture du blé (MB). Les cultures ont été fertilisées conformément aux recommandations formulées pour la région, après analyse du sol. La culture antérieure a les effets suivants sur le rendement du blé : pois de grande culture = engrais vert de trèfle rouge > jachère > canola > blé (MB). Elle exerce peu d'influence sur la concentration de N, de P ou de K dans le grain ou la paille de blé. Le travail du sol n'interagit pas avec l'assolement pour modifier le rendement du blé ou la concentration d'éléments nutritifs. Le régime de travail du sol n'affecte pas le rendement des autres cultures du système de rotation ni leur teneur en éléments nutritifs. La quantité d'engrais azoté requise a diminué lors du deuxième cycle tandis que le rendement du blé a augmenté de 22 % pour le régime NT, comparativement au régime TC. L'étude révèle i) que le pois de plein champ est une culture de remplacement intéressante pour l'engrais vert de trèfle rouge et ii) que les recommandations relatives à l'application d'engrais azoté reposant sur l'analyse du sol devraient tenir compte du système de travail de sol en usage.

“…Therefore, crop residues can have a significant role in nutrient cycling, and since N is usually the nutrient limiting crop production, much attention has been directed to N cycling in residue decomposition, particularly of legume crops. Crop residues have been reported to contribute about 5 to 28% of their N to the subsequent crop (Ladd et al 1983;Muller and Sundman 1988;Bremer and van Kessel 1992;Jensen 1994). In those studies, higher N recovery was associated with legume materials used essentially as green manure, while lower recovery was associated with use of mature legume or cereal straw with high C:N ratio.…”

Soon, Y. K. and Arshad, M. A. 2004. Tillage, crop residue and crop sequence effects on nitrogen availability in a legumebased cropping system. Can. J. Soil Sci. 84: 421-430. A field study was conducted to determine the effects and interactions of crop sequence, tillage and residue management on labile N pools and their availability because such information is sparse. Experimental treatments were no-till (NT) vs. conventional tillage (CT), and removal vs. retention of straw, imposed on a barley (Hordeum vulgare L.)-canola (Brassica rapa L.)-field pea (Pisum sativum L.) rotation. 15 N-labelling was used to quantify N uptake from straw, below-ground N (BGN), and fertilizer N. Straw retention increased soil microbial biomass N (MBN) in 2 of 3 yr at the four-leaf growth stage of barley, consistent with observed decreases in extractable soil inorganic N at seeding. However, crop yield and N uptake at maturity were not different between straw treatments. No tillage increased soil MBN, crop yield and N uptake compared to CT, but had no effect on extractable soil inorganic N. The greater availability of N under NT was probably related to soil moisture conservation. Tillage effects on soil and plant N were mostly independent of straw treatment. Straw and tillage treatments did not influence the uptake of N from its various sources. However, barley following pea (legume/non-legume sequence) derived a greater proportion of its N from BGN (13 to 23% or 9 to 23 kg N ha -1 ) than canola following barley (nonlegumes) (6 to 16% or 3 to 9 kg N ha -1 ). Fertilizer N constituted 8 to 11% of barley N uptake and 23 to 32% of canola N uptake. Straw N contributed only 1 to 3% of plant N uptake. This study showed the dominant influence of tillage on N availability, and of the preceding crop or cropping sequence on N uptake partitioning among available N sources.

Les auteurs ont effectué une étude sur le terrain afin d'établir les effets et les interactions de la succession des cultures, du travail du sol et de la gestion des résidus de récolte sur les réserves et la disponibilité du N labile, car on sait peu de choses en la matière. Les traitements examinés étaient les suivants : non-travail (NT) contre travail ordinaire (TO) du sol et retrait ou rétention de la paille dans un assolement orge (Hordeum vulgare L.)-canola (Brassica rapa L.)-pois de grande culture (Pisum sativum L.). Les auteurs ont recouru au marquage par le 15 N pour quantifier l'absorption du N venant de la paille, du sol (NS) ou de l'engrais. La rétention de la paille a accru le N de la biomasse bactérienne (NBB) deux années sur trois au stade de la quatrième feuille, ce qui concorde avec la diminution du N minéral extractible présent dans le sol aux semis. Toutefois, le rendement et l'absorption de N à maturité ne varient pas avec le traitement de la paille. Comparativement au travail ordinaire du sol, le non-travail accroît le NBB, le rendement et l'absorption du N, sans agir sur la quantité de N minéral extractib...
