Organic amendments are often used to mitigate the effects of soil degradation caused by erosion. In spring 1992, a desurfaced soil (∼15 cm depth mechanically removed to simulate erosion) received one-time applications of amendments (20 Mg ha−1dry wt), and was subsequently seeded annually to spring wheat (Triticum aestivum L.). By 2009, six treatments (fresh and old cattle manure, hog and poultry manure, alfalfa (Medicago sativa L.) hay and straw+200 kg P ha−1) had cumulative yields which were not significantly different (−6.5 to −19.5%) from the topsoil check treatment (no topsoil removed, no amendment). Most (8 of 13) amendment treatments showed significant power function relationships between cumulative grain yield (expressed as a percent of topsoil check) and time while two (hog and poultry manure) were quadratic. Soil organic carbon (SOC) accrued on all treatments over time, increasing significantly from an average of 12.2 g kg−1in 1992 to 13.2 g kg−1(0–15 cm depth) in 2003. Residual amendment effects on total nitrogen (N) and phosphorus (P) were apparent 11.5 yr after application. Results demonstrated that while drastically disturbed soils may recover productivity in the absence of organic amendments (e.g., eroded check treatment), organic amendments play a residual role in their ongoing maintenance.

Northern Alberta

Twelve crops of wheat (Triticum aestivum L.) were grown over a 15-yr period after forage hay swards or a fallow-wheat rotation (control) on a fine-textured soil in northern Alberta. Nitrogen fertilizer was not applied to the forage crops nor to the wheat. Yields of wheat following alfalfa (Medicago sativa L.) ranged from 66 to 114% greater than those following control for the first eight crops. Yield differences started to decline thereafter, although the wheat yield after alfalfa was significantly higher than that after the control for the 10th crop in the 13th year after the sward breaking. The alfalfa contributed to the wheat yields through both the subsoil and topsoil as determined by interchanging topsoil between the former alfalfa and control plots. Yields of wheat after an alfalfa and bromegrass (Bromus inermis Leyss.) mixture were only slightly less than those after alfalfa alone, however, those after bromegrass alone were much less than those following alfalfa. Key words: Alfalfa, bromegrass, yields of subsequent wheat

Over Time

Crop residues are an important source of plant nutrients. However, information on the various methods of residue management on micronutrients in soil and wheat (Triticum aestivum L.) over time is limited. A long-term (84-year) agroecosystem experiment was assessed to determine the impact of fertilizer type and methods of crop residue management on micronutrients over time under dryland winter wheat-fallow rotation. The treatments were: no N application with residue burning in fall (FB), spring (SB), and no residue burn (NB); 45 kg N ha−1 with SB and NB; 90 kg N ha−1 with SB and NB; pea vines; and farmyard manure (FYM) and a nearby undisturbed grass pasture (GP). Wheat grain, straw, and soil samples from 1995, 2005, and 2015 were used to determine tissue total and soil Mehlich III extractable Mn, Cu, B, Fe, and Zn, and soil pH. After 84 years, extractable Mn and B in the top 10 cm of soil decreased in all plots, except for B in FYM and SB. The FYM plots had the highest extractable Mn (114 mg kg−1) in the top 10 cm soil; however, it declined by 33% compared to the GP (171 mg kg−1). Extractable Zn in the top 10 cm of soil increased with FYM while it decreased with inorganic N application in 2015; however, total Zn in grain increased by 7% with inorganic N (90 kg ha−1) application compared to FYM application. The results suggest that residue management had similar impact on soil micronutrients. Inorganic N and FYM application can be integrated to reduce micronutrient losses from cultivation.

Changes In Soil Properties

Changes in soil properties reflect the success or failure of reclamation practices on abandoned wellsites. We examined the effect on soil properties of four (0, 50, 100 and 150%) topsoil replacement depths (TRD) and five amendment treatments [compost, manure, wheat (Triticum aestivum L.) straw, alfalfa (Medicago sativa L.) hay, check] aimed at reclaiming three wellsites (Strathmore, Hesketh and Rosedale) in southcentral Alberta. TRD treatment differences were consistent across all wellsites, with 30 to 32% higher soil organic carbon (SOC) on the 150% TRD compared to the 0% TRD. Initially, the alfalfa treatment showed higher levels of nitrate-nitrogen (e.g., 26 mg kg-1 vs. 3 to 7 mg kg-1 for the other amendment treatments in the 15- to 30-cm depth at Strathmore in fall 1998), which was related to its rapid breakdown and mineralization of organic N. After 40 mo (June 1997-October 2000), the average amounts (n = 3 wellsites) of added C conserved near the soil surface were: compost (65 ±10% SE) > manure (45 ±16% SE) > alfalfa (28 ±11% SE) > straw (23 ± 6% SE). Our results show that organic amendments play an important role in improving soil properties related to long-term productivity of reclaimed wellsites, especially where topsoil is scarce or absent. Key words: Wellsite reclamation, topsoil depth, organic amendments, soil quality

Experiments were conducted to determine the effect of Sea Crop (SC 16) and Ergostim on the yield and nutrient composition of a few crops. Studies conducted under greenhouse and field conditions showed that the yields of wheat (Triticum aestivum L.) and peas (Pisum sativum L.) were not affected by the addition of SC16. The nitrogen (N) and sulfur (S) concentrations of the two crops were not affected by SC 16, except in the control and SC 16 treatment only where the increases were likely due to a concentration effect, since these two treatments had lower yields. Boron (B) and molybdenum (Mo) concentrations in the plants were significantly affected by B and Mo applications, but not by SC 16. A greenhouse study showed that the yields of alfalfa (Medicago sativa L.) and wheat were not affected by the addition of Ergostim. The addition of Ergostim did not affect the N or S concentration of wheat or three cuts of alfalfa.

A qualidade do solo em plantio direto está relacionada ao sistema de culturas e pode ser avaliada pelo teor de matéria orgânica particulada (>53 ∝m), em razão da funcionalidade que essa fração proporciona ao solo e à sua sensibilidade às diferenças de manejo. Visando estudar a qualidade do solo em sistemas de culturas em plantio direto, este trabalho foi conduzido em experimento de longa duração (21 anos) em Latossolo Vermelho distrófico típico nos Campos Gerais do Paraná. Seis sistemas de culturas foram avaliados, em que trigo-TR (Triticum aestivum L.), soja-SO (Glycine max L.), milho-MI (Zea mays L.), aveia-preta-AV, para cobertura (Avena strigosa Schreb.), ervilhaca-ER, para cobertura (Vicia villosa Roth); azevém-AZ, para feno (Lolium multiflorum Lam.); ou alfafa-AL, para feno (Medicago sativa L.) compuseram os seguintes sistemas: TR-SO (referência), ER-MI-AV-SO-TR-SO, ER-MI-TR-SO, AV-MI-TR-SO, AZ-MI-AZ-SO e AL-MI (milho a cada três anos). Os estoques de carbono orgânico total (COT), nitrogênio total (NT) e de C e N na matéria orgânica (MO) particulada (>53 µm) e associada aos minerais (<53 µm) foram determinados em 0-5, 5-10 e 10-20 cm. O sistema semiperene AL-MI apresentou os maiores estoques de COT e NT na camada de 0-20 cm (63,6 Mg ha-1 COT e 4,6 Mg ha-1 NT), com incrementos anuais de 0,23 Mg ha-1 COT e 0,03 Mg ha-1 NT, em relação ao sistema TR-SO. O sistema AL-MI também teve os maiores estoques de C e N na MO particulada nessa camada (12,5 e 0,91 Mg ha-1, respectivamente), por causa da maior adição de fitomassa pelas raízes e a proteção física dos resíduos orgânicos. Os menores estoques de COT e NT na camada 0-20 cm ocorreram no sistema ER-MI-TR-SO (57,8 Mg ha-1 COT e 4,03 Mg ha-1 NT), sem apresentar incremento anual em relação ao sistema TR-SO. Os estoques de C e N na MO particulada foram de 10,4 e 0,67 Mg ha-1, respectivamente. Essa tendência repetiu-se para as camadas individuais, com diferença significativa entre os sistemas na camada de 0-5 cm e não significativa, para as de 5-10 e 10-20 cm. Na média dos sistemas, a MO particulada contribuiu em torno de 30 % para o estoque total de C na camada 0-5 cm. Rotação de culturas com espécies que tenham sistema radicular ativo por mais tempo, como o sistema semiperene AL-MI, tem potencial de incrementar o estoque total de C e N, especialmente da fração MO particulada, proporcionando funcionalidade ao solo e, consequentemente, qualidade.
