The deep furrows and additional liming can improve soil quality and reduce drought impact during coffee plant establishment, especially in dense soils. However, the effects of the initial preparer in the medium to long term are scarce. This study aims to assess the five-year impact of different deep tillage strategies and chemical fertility improvement of the planting furrow on soil physical quality and plant growth under Cambisol with coffee cultivation. The experiment was conducted in a Cambisol in Nazareno, Minas Gerais state, Brazil. The experiment followed a randomized complete block design with a split-plot arrangement in space, including three blocks, six soil depths (0–0.05, 0.15–0.20, 0.35–0.40, 0.55–0.60, 0.60–0.70, and 0.75–0.80 m), and five soil preparation methods: SP40, furrower at 0.40 m with conventional fertilization; SP60, rotary hoe at 0.60 m with additional liming (SP60AL); SP80, soil homogenizer at 0.60 m and subsoiler at 0.80 m with additional liming (SP80AL). These soil preparations were compared with a native savannah vegetation area from the Cerrado biome (Natural). Undisturbed samples were collected at different depths five years after the initial soil preparation. In these samples, physical quality indicators were investigated along with the correlation of plant measurements (stem diameter - SD, plant height - PH, and normalized difference vegetation index - NDVI). Analysis of variance and the Scott-Knott and Dunnett tests (p < 0.05) were applied to analyze the data. After five years of soil preparation, improvements up to 0.40 m depth were due to soil homogenization, subsoiling, and liming, reducing bulk density and enhancing water retention. Additional limestone between 0.20 and 0.60 m depth improved SD, PH, and NDVI, mitigating drought. However, initial soil preparation induced compaction at 0.60–0.70 m depth, with subsoiler effects disappearing at 0.80 m. Effective deep tillage improves soil quality but requires careful planning.

咖啡种植沟中的深耕土壤对改善土壤物理质量和增强致密土壤中的植物活力具有持久的益处
深沟和额外的石灰可以改善土壤质量并减少咖啡树建立过程中的干旱影响,尤其是在致密的土壤中。然而,初始编制者在中长期内的影响是微乎其微的。本研究旨在评估 Cambisol 咖啡种植下不同深耕策略和种植沟化学肥力提高对土壤物理质量和植物生长的五年影响。该实验是在巴西米纳斯吉拉斯州纳扎雷诺的 Cambisol 进行的。该试验遵循随机完全区组设计,在空间上采用裂区排列,包括三个区块、六个土壤深度(0-0.05、0.15-0.20、0.35-0.40、0.55-0.60、0.60-0.70 和 0.75-0.80 m)和五种土壤准备方法:SP40,0.40 m 的犁沟,常规施肥;SP60,0.60 m 处的旋转锄头,带附加石灰 (SP60AL);SP80,土壤均质机在 0.60 米处,深松机 在 0.80 米处,带有额外的石灰 (SP80AL)。将这些土壤准备与来自 Cerrado 生物群落(自然)的原生稀树草原植被区进行了比较。在初始土壤准备 5 年后,在不同深度收集未受干扰的样品。在这些样品中,研究了物理质量指标以及植物测量值(茎直径 - SD、植物高度 - PH 和归一化差异植被指数 - NDVI)的相关性。应用方差分析和 Scott-Knott 和 Dunnett 检验 (p < 0.05) 分析数据。经过五年的土壤整备,由于土壤均质化、深松和石灰化,降低了堆积密度并增强了保水性,因此深度提高了 0.40 m。深度在 0.20 至 0.60 m 之间的额外石灰岩改善了 SD、PH 和 NDVI,缓解了干旱。 然而,初始整土在 0.60-0.70 m 深度引起压实,深松机效应在 0.80 m 处消失。有效的深耕可改善土壤质量,但需要仔细规划。
