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（L.）在加拿大是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 Orchards是北美最大的haskap种植者（>105公顷），但他们的主要挑战是缺乏加拿大或北美适当研究的生育计划的建议。因此，种植者采用了其他基因无关植物作为基准的建议，导致低和不一致的haskap植物生产力和水果质量。拟议研究的目的是为北45果园开发一个综合养分管理（INM）计划，使用自然改良剂，减少对合成肥料的依赖，并提高其haskap植物的生产力。我们的研究和其他人的研究表明，焦木酸（PA），堆肥充电生物炭和海藻（Ascophyllum nodosum）提取物（ANE）对其他植物的生长，保护和产量显着的功效，但没有测试haskap。因此，本研究的短期目标是：（1）评价PA-ANE混合物的施用量和施用频率对两个商品化haskap品种“靛蓝Gem”和“Wojtek”生长发育的影响;（2）评价haskap植物对氮（N）、磷（P）和钾（K）肥料在桑迪壤土和粘性土壤中的反应;（3）研究了生物质炭和氮磷钾肥料在稻田综合管理中的联合效应;（4）研究了PA-ANE混合物在稻田综合管理中的生物刺激效应;（5）分析了稻田综合管理的经济效益。新的知识将产生的机制haskap植物养分吸收，浆果生产和提高其对人类营养和健康的好处。North 45 Orchards将利用这些成果增加收入和就业，并为加拿大haskap产业的扩张做出贡献。
