Haskap (Lonicera caerulea L.) is a relatively new crop in Canada and tremendously rich in polyphenols and other bioactive compounds with significant anti-inflammatory properties. North 45 Orchards is the largest haskap grower (>105 ha) in North America but their major challenge is the lack of recommendation of a properly researched fertility program in Canada or North America. Therefore, growers have adopted recommendations for other genetically unrelated plants as a benchmark, leading to low and inconsistent haskap plant productivity and fruit quality. The aim of the proposed research is to develop an integrated nutrient management (INM) program for North 45 Orchards using natural amendments, reduce the dependence on synthetic fertilizer and to increase their haskap plants productivity. Our studies and those of others showed remarkable efficacy of pyroligneous acid (PA), compost-charged biochar and seaweed (Ascophyllum nodosum) extract (ANE) on growth, protection and yield of other plants but not tested on haskap. Thus, the short-term objectives of the proposed research are to: (1) assess variations in rate and frequency of application of PA-ANE mix on growth and development of two commercial haskap varieties 'Indigo Gem' and 'Wojtek'; (2) evaluate haskap plant response to nitrogen (N), phosphorus (P) and potassium (K) fertilizers in sandy loam and clayey soils; (3) investigate combined effect of compost-charged biochar and NPK fertilizer in an INM program for haskap; (4) investigate biostimulatory effect of PA-ANE mix on haskap in an INM program; and (5) analyze the economic benefit associated with INM program. New knowledge will be generated on mechanisms of haskap plants nutrients uptake, berry production and enhance its benefits to human nutrition and health. North 45 Orchards will exploit the results to increase revenue and employment, and to contribute to the expansion of the Canadian haskap industry.

Haskap （Lonicera caerulea L.）是加拿大一种相对较新的作物，富含多酚和其他具有显著抗炎特性的生物活性化合物。North 45 orchard是北美最大的haskap种植者（bbbb105公顷），但他们面临的主要挑战是缺乏在加拿大或北美进行适当研究的生育计划的建议。因此，种植者采用其他基因不相关的植物作为基准，导致haskap植物生产力和果实质量低且不一致。本研究的目的是为北45果园开发一个综合营养管理（INM）计划，利用自然改进剂，减少对合成肥料的依赖，提高其haskap植物的生产力。我们的研究和其他人的研究表明，鹿蹄草酸（PA）、堆肥生物炭和海藻（Ascophyllum nodosum）提取物（ANE）对其他植物的生长、保护和产量有显著的效果，但没有在haskap上进行试验。因此，本研究的短期目标是：(1)评估PA-ANE混合物对两种商业haskap品种“Indigo Gem”和“Wojtek”生长发育的施用量和频率的变化；(2)评价砂质壤土和粘性土中haskap植物对氮(N)、磷(P)和钾(K)肥料的响应；(3)探讨生物炭堆肥与氮磷钾肥在土壤磷肥（INM）方案下的联合效应；(4)在INM程序中研究PA-ANE混合物对haskap的生物刺激作用；(5)分析INM方案的经济效益。将产生新的知识，对haskap植物营养吸收机制，浆果生产和提高其对人类营养和健康的好处。北45果园将利用这些成果来增加收入和就业，并为加拿大haskap行业的扩张做出贡献。
