“…Diseased plants were available for the WCT variety alone. Since many of the 61 elds studied had diseased and healthy WCT palms, the total number of sites for healthy plants was 52 each, and the number of diseased plants was 42. All the 61 elds sampled were about one acre each.…”

“…Coconut is a fast-growing and heavily producing perennial crop causing excessive removal of large quantities of nutrients from the soil, and nutrient depletion can be speedy in Coconut palm groves (Somasiri et al 2003). Accordingly, lack of soil fertility and inadequate nutrition are causing a reduction in the yield of Coconut palms, and their cultivation is becoming unsustainable (Subramanian et al 2005; Kalidas et al 2014;Nair et al 2018a; Sudhalakshmi 2021) in many parts of the world, including south India. Continuous crop cultivation alone in an agricultural region over a long period can cause loss of fertility and soil degradation (Lu et al 2023).…”

“…Among the signi cant Coconut growing soils in India, sandy soils are known to have a low amount of soil nitrogen (Khan and Krishnakumar 2018) because of high nitrate loss through leaching from such soils(Malhotra et al 2017), whereas clay content enhances N xation in soils(Thabit et al 2023). In general, Coconut-growing soils in Kerala include clayey, loamy, and sandy types(Nair et al 2018a). In the current study, about 72% of samples were from coastal sandy soil regions and the rest from midland loams.…”

Achieving sustainability in the productivity of crops has become essential in fulfilling the global sustainable developmental goals (SDG), which is impossible without continuous monitoring of the soil fertility status of traditional fields of specific crops worldwide. Palms and palm products, primarily Coconut palm, remain crucial to the world's sustainable rural, urban, and industrial development, especially in the tropics. Accordingly, the current study focuses on the soil fertility status of one of the most intensively Coconut-cultivated regions of South India, Kerala, concerning palm varieties, soil types, health conditions, and agroclimatic zones in two seasons. The data generated is valid globally for better comparison of the soil fertility issues of palm groves worldwide. Comparative account of soil fertility parameters such as soil pH, field water content (FWC), total organic carbon (TOC), soil available nitrogen (SAN), soil available phosphorus (SAP), and soil available potassium (SAK) of palm groves under 14 various soil series are discussed. The soil pH of most Coconut fields remains below seven; nitrogen and potassium are deficient in most fields, whereas carbon and phosphorus are high. The findings suggest the significance of continuous monitoring of NPK nutrient regimes and soil pH and carbon content in the fields for ensuring the sustainability of Coconut production and soil health maintenance in palm fields. Overall, the investigation stands as a model for monitoring crop fields worldwide to ensure food security and safety sustainability, especially in wet tropics, to overcome the climate crisis, and to achieve the targets of SDG 30.
